AGU Town Hall Meeting: Great Earthquakes and their asperities -Kanto Asperity (12/10/08)

AGU Town Hall Meeting: Great Earthquakes and their asperities -Kanto
Asperity
Project (KAP: IODP Complex Drilling Proposal 707)

Date: December 18, 2008 (Thursday)
Time: 18:15 to 19:15
Location: Moscone West, Room: 3020

Drilling, coring, and long-term monitoring of asperities in the
seismogenic zone is one of the most ambitious goals of current programs
investigating the plate boundaries. These efforts may lead to insights
on the mechanisms of great earthquakes and their associated societal impact.
This Town Hall Meeting will introduce the Kanto Asperity Project (KAP)
and associated IODP drilling proposals. The Kanto Asperity Project is a
program designed to investigate asperities associated with destructive
earthquakes in the Kanto region. The Kanto region (Tokyo and the
surrounding area) is one of the most densely populated urban areas in
the world and has been devastated by repeated great earthquakes. The
Kanto region is located at an island arc- island arc collision zone
composed mainly of intensely deformed volcaniclastic, volcanic, and
hemipelagic rocks.
In the Kanto region, KAP is studying the geological background, history
of great earthquakes, and properties and mechanics of asperity/and
adjacent non-asperity regions (slow slip events). We have submitted
proposals for a drilling and geophysical monitoring project, including
IODP (IODP 707-CDP, 707A, and 707B). These proposals request drilling,
coring, and long-term-monitoring at nine sites in and around the
subduction zone. The KAP town hall meeting will outline the substance of
these proposals and the opportunities for international scientific
cooperation. Additionally we seek discussion of KAP, including the types
of earth science investigations needed to study subduction zone
earthquakes, asperities, and earthquake geohazards.

All are welcome.
Refreshments will be provided.

3. EGU 2009, Vienna - Deformation of river networks in orogens

-------------------------------------------------------------
*1. AGU - Continental Scientific Drilling Town Hall Meeting*

You are invited to join DOSECC and ICDP at the third annual Continental
Scientific Drilling Town Hall Meeting, held during the AGU Fall Meeting:

The Thrill to Drill: Continental Scientific Drilling Town Hall Meeting
Monday December 15, 2008

San Francisco, CA
http://www.dosecc.org/town_hall.pdf

Drilling in the Earth's continental crust allows study of otherwise
inaccessible subsurface geological processes and structures. Within the
past decade or so, drilling has led to many important geological
discoveries on paleoclimate, impacts, volcanoes, mantle plumes, active
faults, etc. Two short overview talks by Dennis Nielson (DOSECC) and
Rolf Emmermann (ICDP) will be followed by discussion and a reception to
allow exchange of ideas. All geoscientists interested in using drilling
as a tool are invited.

*2. EGU 2009 Session Seafloor expression of tectonic and geomorphic
processes*

Dear colleagues,

We would like to draw your attention to our session GM9.3 'Seafloor
expression of tectonic and geomorphic processes' during the EGU 2009
meeting, that will be held in Vienna from 19-24 April 2009.

We would like to bring together scientists from a variety of disciplines
(e.g. geomorphology, marine geology and geophysics, modeling,
geotechnics, geochemistry, geodynamics, volcanology) in order to examine
the causes and consequences of the underwater landscape.

The deadline for abstract submission is January, 13th 2009.

A short description of the session is given below.

Seafloor depth records preserves a wealth of information about tectonic
(e.g. fault scarps), geomorphic (e.g. channel erosion and landsliding),
volcanic and geodynamic processes. High quality bathymetry, especially
when combined with sub-seafloor measurement, provides an exciting
opportunity to combine geomorphology and geophysics and to extend
quantitative geomorphology offshore.

This interdisciplinary session aims to examine the causes and
consequences of the underwater landscape. The goal is to stimulate
interdisciplinary work by bringing together researchers who quantify and
characterize the shapes that form the seafloor, seek to understand the
sub-surface processes at work and their impacts, or use bathymetry as a
model input. A range of depths from oceanic (e.g. oceanic plateaus and
abyssal hils), through mid-ocean ridges to accretionary wedges and
continental margin are expected. Datasets from satellite-predicted depth
to ultra high-resolution deep tow swath are anticipated.

We welcome any exciting submissions in the spirit of the session, even
if your particular process or bathymetric expression has not been
explicitly mentioned, e.g.: Hot-spot ridge interaction; Submerged
glacial geomorphology; What governs the relative dominance of canyon
erosion and landsliding as mass wasting processes?

We look forward to your participation and contribution

*3. EGU 2009, Vienna, Deformation of river networks in orogens*

Dear MARGINS community,

We would like to call your attention to the session "Evolution and
deformation of river networks in orogens" at the next European
Geosciences Union Meeting, 19-24 April 2009 in Vienna that may interest
you. We hope to bring as many contributions as possible and exciting
discussions on this emerging yet little addressed topic that crosses
tectonics and surface processes. Abstract are due 13th of January 2009.

GM4

River networks exert a primary control on the evolution of orogens
through the advection of material away from their surfaces. However
fundamental questions are emerging about how river networks evolve over
time, in particular the degree to which river networks are subject
themselves to 'deformation'. For example, is the evolution of river
networks static or ever changing? Can river networks be simply advected
statically across orogens along with rocks and topography or are they
subject to strain imposed by the deforming orogen? Answers to these
questions will increase our capability of using present topography to
understand the past, e.g. by inverting landscape topography or by using
river networks as markers of deformation. We therefore welcome
contributions on any aspect of the kinematics and dynamics of river
networks in deforming orogens ranging from field-based studies and
data-based approaches to conceptual and numerical investigations.

Postdotoral opportunity in magmatism at tectonism at the Hawaiian Volcano Observatory (9/16/08)

Dear Colleagues,

Our apologies for duplicate postings of this announcement.

We would like to let you know about an exciting USGS Mendenhall
Postdoctoral Opportunity that may be of interest to students or postdocs.
The USGS, in collaboration with the University of Alabama, is seeking
applicants to conduct postdoctoral research on the magma plumbing system
of Kilauea volcano, which is currently experiencing an unprecedented
eruptive episode involving vents at both its summit and east rift zone.

The goal of the project is the development and implementation of
conceptually and physically realistic models of Kilauea's shallow magmatic
system that build on existing knowledge of the volcano and that
quantitatively predict the spatial and temporal patterns of recently
observed volcanic activity, seismicity, and deformation. We seek a
researcher who will develop innovative models that take advantage of the
vast archive of geophysical and geological data at Kilauea, and who will
employ new cutting-edge data streams, for example, PS InSAR, high-rate
GPS, gravity, or array seismology.

The Mendenhall program is an exceptional opportunity to conduct research
with the USGS and includes full salary and project funding for two years
(with a possible extension for two additional years). If you are
interested in more information about this project, please don?t hesitate
to contact any one of the project supervisors (listed below), and visit
both the Mendenhall Program website (http://geology.usgs.gov/postdoc/) as
well as the website for this specific research opportunity
(http://geology.usgs.gov/postdoc/2010/opps/opp31.html).

The application deadline for this opportunity is November 12, 2008. The
successful applicant will be expected to have completed their PhD and
start work at the Hawaiian Volcano Observatory in late 2009 or early 2010.

AGU U09: Asthenosphere Session (9/3/08)

Dear Collagues,

We encourage you to participate in the multi-disciplinary session:
Different Views on One Asthenosphere" at the 2008 AGU fall meeting
in San Francisco.

We are very pleased to present as invited speakers

Karsten Bahr, University of Göttingen
Clint Conrad, University of Hawaii
Colleen Dalton, Boston University
Alberto Saal, Brown University

U09: Different Views on One Asthenosphere

It is generally accepted that the asthenosphere is a mechanically weak
region in the shallow mantle underneath the lithosphere. Even so, every
discipline has a different perspective on what the asthenosphere is. For
example, it has been termed the low (seismic) velocity zone and the
low-viscosity zone, and its unique properties have been attributed to
either mineral properties at relevant temperatures and pressures or to
the presence of melt and/or water.

While we have a good understanding of some of the asthenosphere's
properties and know of the importance of this thin layer as it
influences mantle flow, we are still seeking a unified picture that
includes independent constraints from all relevant disciplines.

In this session we will explore different views on the asthenosphere to
(1) identify first order characteristics (e.g. location, depth,
viscosity, seismic velocity, anisotropy, attenuation, electrical
conductivity, density, flow field, lateral variations) and (2) combine
observations to provide a forum to discuss a unified picture of the
asthenosphere.

Submission deadline is 10 September 2008. (You can submit at
http://submissions3.agu.org/submission/entrance.asp)

We look forward to learning about your recent work!

3 Fall AGU Session Announcements (8/14/08)

1. Session V14: High Field Strength Elements
2. Session U25: Integrated Geohazards along Continental Margins and
Plate Boundary Zones
3. Session T26: Microplate Geodynamics

---------------------------------------------------------------------------------------

1. Session V14 on High Field Strength Elements

Dear Colleagues,

We would like to call your attention to a special session at the 2008
AGU Fall Meeting relating to the cycling of high field strength elements
from subduction zones to the deep mantle and back to the surface in
mantle plumes. Session V14 "From Subduction Zones to Mantle Plumes:
High Field Strength Elements as Geochemical Tracers of Crustal
Recycling" is
intended to bring together a confluence of information provided by
experimental, dynamical and geochemical studies that helps to unravel
subduction zone processes, and ultimately detect the signatures of the
recycled materials in hotspot lavas. While the session will highlight
experimental and geochemical studies that utilize HFSE as tracers of
subduction zone processes and whole mantle recycling, presentation of
other geochemical indicators that help constrain these processes such as
Ni in olivine as a proxy for eclogite melting, radiogenic isotope (Os,
Sr, Nd, Pb, etc.) signatures for crustal recycling, noble gas and
volatile signatures for crustal melting beneath arcs and recycling into
hotspots, is very much encouraged.

We hope that you will consider submitting an abstract to this session.

Best regards,
Glenn Gaetani
Matt Jackson

V14: From Subduction Zones to Mantle Plumes: High Field Strength
Elements as Geochemical Tracers of Crustal Recycling

Large quantities of oceanic and continental crust are known to enter the
mantle at subduction zones, and some of this material may become
entrained in mantle upwellings, or plumes, imparting a geochemical
signature on hotspot lavas. However, following injection into the
mantle, the composition and fate of subduction zone-processed material
is little known, making the signatures associated with recycled oceanic
crust difficult unambiguously identify. This owes, in large part, to the
complex processes that operate in subduction zones, including phase
changes and dehydration or partial melting of the subducted oceanic
lithosphere. Many of the elements frequently used as geochemical tracers
for subduction are volatile and/or fluid mobile and appear to be largely
lost from the subducted lithosphere during dehydration and/or partial
melting. High field strength elements (HFSE), such as Ti, Zr, Hf, Nb,
and Ta, are thought to behave conservatively during subduction zone
processing, providing a unique tools for understanding subduction zone
processes and identifying recycling signatures in hotspot lavas. This
session is intended to bring together a confluence of information
provided by experimental, dynamical and geochemical studies that helps
to unravel subduction zone processes, and ultimately detect the
signatures of the recycled materials in hotspot lavas. While the session
will highlight experimental and geochemical studies that utilize HFSE as
tracers of subduction zone processes and whole mantle recycling,
presentation of other geochemical indicators that help constrain these
processes such as Ni in olivine as a proxy for eclogite melting,
radiogenic isotope (Os, Sr, Nd, Pb, etc.) signatures for crustal
recycling, noble gas and volatile signatures for crustal melting beneath
arcs and recycling into hotspots, is very much encouraged.

2. Session U25: Integrated Geohazards along Continental Margins and
Plate Boundary Zones

Dear colleagues -

We would like to bring your attention to the following AGU Union special
session that provides a unique opportunity to showcase your MARGINS and
related research, and its societal relevance. Please consider
submitting an abstract to this session.

*U25: Integrated Geohazards along Continental Margins and Plate Boundary
Zones*

An ancillary but significant product of investigations along continental
margins and plate boundary zones (e.g., through the NSF MARGINS Program,
ODP/IODP, and related programs) has been a broader, highly integrated
understanding of the scientific causes and resulting impacts of
geohazards. Examples include, but are not limited to, (1) rheologic and
structural controls on plate boundary seismogenesis and tsunamigenesis;
(2) stratigraphic, chemical, and geomechanical factors that promote
weakening and failure; (3) climatic, tectonic, and anthropogenic
influences on rates of sediment erosion, transport and deposition, and
impacts on our coastlines, and (4) explosive volcanism, and the role of
magma composition and volatile flux in eruptive behavior. Although
geologic settings may differ, they share many common processes and
conditions that contribute to hazardous phenomena; therefore a broad,
cross-disciplinary discussion could benefit many scientific
communities. To foster these discussions, we solicit contributions that
address the wide range of margin-related geologic hazards, their causes,
and their consequences. Field, laboratory, and numerical studies are
welcome.

3. Session T26: Microplate Geodynamics

Dear Colleague,

Suzanne Baldwin and I would like to encourage you to consider making a
presentation at a special session at AGU we are convening entitled
"Microplate Geodynamics". The detailed session information is listed
below. We ask that you share this email with students and colleagues who
may be interested. Please note that the AGU abstract deadline is
September 10, 2008 (23:59 Universal Time). For more information, please

Session #: T26 Title: Microplate Geodynamics Sponsor: Tectonophysics.
CoSponsors: Geodesy, Geomagnetism and Paleomagnetism, Seismology,
Volcanology, Geochemistry, and Petrology. Description: Microplates form
and evolve at convergent, transform, and divergent boundaries between
large lithospheric plates. These fault-bounded lithospheric fragments
preserve complex geologic and tectonic histories as they evolve over
relatively short spatial and temporal timescales, and rotate relative to
neighboring (micro)plates. Their evolution has important implications
for the recycling and exchange of material between crust and mantle,
terrane accretion, as well as the exhumation of high and
ultrahigh-pressure rocks. We invite contributions from the fields of
geodynamics, geophysics, geodesy, geology, geochemistry etc. that seek
to understand how microplates evolve in space and time, including
active, ancient or analog examples. Contributions that highlight
interdisciplinary approaches to the study of the four dimensional
evolution of microplates, including their formation, growth and
destruction, are especially encouraged.

Nankai Seismogenic Zone - AGU Session T-22 Announcement (8/14/08)

Colleagues,

Please consider submitting an abstract to the following special
session, organized to highlight all research related to the
seismogenic zone of the Nankai Trough subduction system.

SESSION T22: Plate Boundary Processes in the Nankai Trough
Subduction Zone

Conveners: Harold J. Tobin (Un. of Wisconsin, USA) and Masataka
Kinoshita (JAMSTEC-IFREE, Japan)

The Nankai Trough has become an iconic subduction zone for the
investigation of forearc tectonic processes and great subduction
earthquakes. It is perhaps the most intensively-studied
convergent plate boundary in the world. Recent work here ranges
from the discovery of deep, non-volcanic tremor and VLF
earthquakes, through detailed seismic tomography of subducting
plate and forearc wedge structure, high resolution 3D seismic
reflection surveys and, most recently, direct sampling through
scientific drilling. This multi-disciplinary session will
highlight the results of the just-completed first stage of IODP
drilling in the NanTroSEIZE project, as well as recent 3D
seismic reflection imaging, novel seismological observations,
and geodetic studies. Contributions are welcomed on any topic
related to the Nankai forearc and plate boundary processes,
including accretionary wedge architecture, state of stress,
fault zone structure, fluid-fault interaction, megathrust
earthquakes, tsunamigenesis, and tremor and VLF seismic events.

Session Announcement for AGU (8/6/08)

Dear colleagues,

We would like to encourage you to submit you latest research to the
session we organize at the next AGU in San Francisco (15-19 December
2008). We hope to bring together geochemists, petrologists,
geophysicists and all those interested by the subduction zones to
contribute to make the session a big success.

V06: Subduction Zones: Geochemical Processes and Geophysical Constraints
Sponsor: Volcanology, Geochemistry, and Petrology
CoSponsor: Mineral and Rock Physics, Seismology. Tectonophysics

Description: Subduction zones are one of the most geologically
dynamic and scientifically exciting areas of the earth because they are
the place where old crust is destroyed and new crustal material is
created. They also are responsible for most of the volcanoes and produce
most of the largest earthquakes and tsunamis. This session aims at
evaluating the geochemical processes and budgets of subduction zones and
the associated petrological processes. We welcome contributions focused
on (a) the chemical and isotopic budget of the subducted material (the
input sediments and crust), (b) the composition of the volcanic arcs,
back-arcs and fore-arc basins and their origins, (c) the effects of the
presence of volatiles on the melting conditions in the mantle wedge, (d)
the seismic and other geophysical characteristics of the materials of
the mantle wedge that constrain compositions and processes, and
establish mass transfer estimations and (e) physical and numerical
modeling of mass transfer in subduction channels and mantle wedge.
Integration of these different approaches should help our community to
decipher the complex processes occurring in key areas of our planet and
by consequence to better understand long-term contribution of subduction
processes to its evolution.

We hope to meet you soon in San Francisco!

Do not miss the deadline for submitting your abstract: 10 September 2008

2 AGU Session Announcements (8/5/08)

1. Gulf of California - Salton Trough MARGINS Boundary System
2. Minerals, Inclusions and Volcanic Processes

----------------------------------------------------------------------------------------------------

1. Gulf of California - Salton Trough MARGINS Boundary System

AGU Session Announcement: Recent Advances in Understanding the Gulf of
California - Salton Trough Plate Boundary System: Along Strike and
Through Time

We would like to draw your attention to a special session at the Fall
AGU meeting that will examine the Gulf of California - Salton Trough
MARGINS focus site. We encourage submission of abstracts on recent
research and/or novel ideas from any relevant geoscience discipline, in
the terrestrial or marine realms, that contributes to understanding this
plate boundary over the past ~12 million years. Please share this
announcement with interested people who might not have received this
message.

SESSION T42: Recent Advances in Understanding the Gulf of California -
Salton Trough Plate Boundary System: Along Strike and Through Time

CONVENERS: Paul J. Umhoefer (paul.umhoefer at nau.edu), Michael Oskin
(oskin at geology.ucdavis.edu), Rebecca Dorsey (rdorsey at uoregon.edu), Joann
Stock (jstock at gps.caltech.edu)

DESCRIPTION: The Gulf of California - Salton Trough is an active
oblique-divergent plate boundary. Despite similar rates of relative
plate motion along strike, major differences in rifting style have been
expressed along the boundary and through time since 12 Ma. Many
parameters and processes along the plate boundary may have affected
rifting style, including strain partitioning, localization of strain,
width of rift domains, and the role of magmatism, low-angle normal
faults, and sediment flux in surface to upper mantle processes. The
Colorado River has produced a large sediment flux since 5 Ma that
dominates the north while the south is sediment-starved. The role of
varying climate and tectonics is an emerging research theme as the
boundary spans from temperate to tropical zones. The total offset across
the plate boundary and its temporal development is controversial. How
the northern part of the system in the Salton trough ties northward into
the broader Pacific - North America boundary is also incompletely
understood. This session welcomes contributions from recent research or
novel ideas from any relevant research, terrestrial or marine, that
contributes to understanding this plate boundary over the past 12
million years.

2. Minerals, Inclusions and Volcanic Processes

Colleagues,

Please consider submitting an abstract to the following special
session at the upcoming Fall AGU meeting (15-19 December). The abstract
deadline is September 10. Apologies for multiple posts.

INVITED SPEAKERS: Alex Sobolev, Maxim Portnyagin, Glenn Gaetani,
Elizabeth Cottrell.

The last two decades have witnessed a dramatic growth in interest in
studies of melt inclusions, small portions of melt trapped by
crystals growing during magma evolution. One important area of
application for melt inclusion research is the study of primitive
mantle-derived magmas. These are commonly modified prior to eruption
by fractionation, degassing, assimilation and other processes, with
melt inclusions potentially providing snapshots of the early
crystallisation environment. Increasing interest in melt inclusions
has also stimulated theoretical, petrological and experimental
studies aimed at understanding the processes that lead to melt
inclusion trapping and post-entrapment modification. This session,
complementing the short-course for the new Reviews in Mineralogy and
Geochemistry volume Minerals, Inclusions and Volcanic Processes,
will focus on important and topical questions in the field of melt
inclusions research: What does the melt inclusion record actually
represent? How much is this record modified by post-entrapment
processes? What unique information is provided by melt inclusions?
How does this information tie in with broader topics in basaltic
petrogenesis? We welcome contributions based on studies of natural
samples and/or experimental and theoretical studies of melt inclusion
formation and modification.

Please forward this information to any interested students,colleagues or
other interested parties.

AGU session OS33: Coastal Geomorphology and Morphodynamics (7/31/08)

Greetings,
We wish to encourage submission of abstracts to the following AGU
session at The Fall Meeting in San Francisco (Dec 15-19). Abstracts
are due Sept 10.

OS33: Coastal Geomorphology and Morphodynamics

Coastal environments and landforms evolve in response to winds,
waves, tides, currents, sediment delivery, and relative sea level
fluctuations at a wide range of time and space scales. In light of
climate change-induced sea level rise, coastal geomorphology has
particular relevance to society because of the high density of human
population near the coast. This session welcomes contributions on
recent advances in coastal geomorphology and morphodynamics from a
variety of geomorphic settings (including rocky coasts, barrier
islands systems, open ocean coasts, sheltered/semi-enclosed bays,
uniform and mixed sediment beaches) at a variety of timescales
(event, seasonal, interannual through decadal, and century through
Quaternary), with particular emphasis on the feedbacks between
changes in morphology and forcing agents. Contributions based upon
field measurements, application and development of models, or
investigation of sedimentary deposits are encouraged.

Job Opportunities with USGS (7/29/08)

Dear colleague,
I want to bring to your attention our plan to advertise shortly for a
research scientist position in marine geology/geophysics at the USGS
Woods Hole Science Center. The center is located within the campus of
the Woods Hole Oceanographic Institution.
Please, follow the official announcement or contact me for details.

Separately we also seek a post-doctoral candidate to quantitatively
evaluate the tsunami hazard to the U.S. Gulf of Mexico and Atlantic
coasts. This two-year position, to start in October 2009, is part of the
USGS Mendenhall post-doctoral fellowship program. Details about the
program can be found at geology.usgs.gov/postdoc/. The official
announcement is attached.

Uri ten Brink (508) 457-2396, utenbrink@usgs.gov

Official annoucement for the Mendenhall post-doc:
2. Quantitative evaluation of tsunami hazard to the Gulf of Mexico
and Atlantic coasts

Tsunamis are among the world=92s most destructive coastal hazards. The
sharp increase in coastal population density, the intense development of
harbors and urban infrastructure, tourism, and the exploitation of
mineral resources in coastal areas, all set up a potential disaster of
catastrophic proportions. Although the frequency of tsunamis along the
Atlantic and Gulf of Mexico coasts of North America is low, tsunamis in
this region are a serious concern to policy makers and ordinary citizens
because of the dense infrastructure and population along the shoreline.
Major infrastructure projects, such as nuclear reactors, are designed
with consideration for a catastrophic event over a long time period
(10,000 years). Following the surge in application for licenses to build
new nuclear reactors along the Gulf and Atlantic Coasts, the USGS was
approached by the U.S. Nuclear Regulatory Commission to conduct research
that will help with the assessment of tsunami hazards to these coasts.

We seek a post-doctoral candidate to quantitatively evaluate the
tsunami hazard to the U.S. Gulf of Mexico and Atlantic coasts. The major
hazard to these coasts appears to arise from landslide-generated
tsunamis. The successful candidate will compile and analyze various data
including multibeam bathymetry, seismic reflection data, earthquake
data, and cores along the continental slope of the Gulf and Atlantic
coasts to evaluate and date the distribution of landslides in these
regions. The successful candidate will investigate theories and
observations regarding the effects of slide speed and bottom friction on
the amplitude of tsunamis and will use in-house software packages to
model the effects of potential landslide sources on selected coastal
segments of the Gulf and Atlantic coasts. The successful candidate is
expected to interact with the NOAA PMEL lab regarding modeling
techniques and with university scientists regarding landslide dynamics
to enhance the quality of their research. Postdoctoral candidates in the
fields of geophysics, geology (with a strong background in computer
simulations), or civil engineering are encouraged to apply. The
successful candidate will pursue their work both in Woods Hole, MA, and
Menlo Park, CA.

Tsunami research is a young and exciting interdisciplinary field that
bridges between geology, solid earth geophysics, seismology, civil
engineering, and hydrodynamics. In particular, little is known about
submarine landslides, their excitation by ground shaking, and the
coupling between landslide and the overlying water layer. The USGS is
emerging as a leader in this field because of its diverse expertise. The
successful candidate will promote USGS leadership in tsunami science.

Proposed Duty Station: Woods Hole, MA; Menlo Park, CA

Areas of Ph.D.: Geology, geophysics, engineering

Qualifications: Applicants must meet one of the following
qualifications: Research Geologist, Research Geophysicist, Research Engineer

(This type of research is performed by those who have backgrounds for
the occupations stated above. However, other titles may be applicable
depending on the applicant's background, education, and research
proposal. The final classification of the position will be made by the
Human Resources specialist.)

Central American Subduction System

Guest Editor(s): G. Alvarado, K. Hoernle, E. Silver

Description: This theme invites papers covering all disciplines and
aspects of the Central American Subduction System. Topics include (but
are not restricted to) the composition, age, structure, diagenetic,
metasomatic, and metamorphic reactions within the subduction input
(incoming and subducting plates) and processes occurring within,
structure of and output from the fore arc, volcanic arc, back arc, and
mantle wedge. Of particular interest are studies that (1) link processes
occurring in different parts of the subduction system, for example,
relationship between subduction input and output in the fore arc and
volcanic arc, material fluxes through the system, how differences in
subduction parameters (e.g., slab dip, crustal/lithospheric thickness)
or mantle wedge structure/composition affect magma composition, the
relationship between fluid release and seismic activity, (2)
characterize the temporal and spatial evolution of the subduction system
(e.g., changes in angle and dip of the subucting slab, fore-arc fluid
venting, and in the structure, chemistry, explosive activity, and
eruption rates of the volcanic arc), and (3) address the long- and
short-term hazards related to the subduction zone, such as the origin
and consequences of earthquakes, submarine and subaerial landslides/mass
wasting, tsunamis, and volcanic activity (eruptions and gas venting). By
the end of this decade, the Central American subduction system will be
one of the best studied on Earth. A major goal of this theme will be to
integrate the considerable international efforts that have been focused
on the Central American subduction system (e.g., U.S. Margins program,
German Collaborative Research Center SFB574, CRISP Drilling into the
seismogenic zone) with local projects carried out by geoscientists
throughout Central America. It is expected that this theme will remain
open for 3 years.

Two GSA 2008 Meeting Sessions (5/19/08)

1. Mixed Siliciclastic-Carbonate Systems: Mixing through Time and Space
2. Lithospheric Structure and Geologic Evolution of the Gulf of Mexico Passive
Margin

____________________________________________________________________

1. Announcement of session on Mixed Siliciclastic-Carbonate Systems: Mixing
through Time and Space; GSA Annual Meeting Houston, 5-9 October 2008

Dear Colleagues,

We are writing to request abstract submissions for a technical session at the
Joint GSA/GCAGS/HGS Annual Meeting to be held 5-9 October 2008 in Houston.

The session is titled Mixed Siliciclastic-Carbonate Systems: Mixing
through Time and Space. Carbonate and siliciclastic sediments/strata are
typically studied separately.However, there are numerous examples both in the
rock record and in modern environments where these sediment types interact on
various temporal and spatial scales. The interaction of carbonate and
siliciclastic sediments has been poorly studied and remains a gap in the
stratigraphic community's understanding of sedimentary systems. This session
will foster discussion of mixed systems by bringing together carbonate and
siliciclastic stratigraphers.

If you can share work on mixed systems, please consider submitting an abstract
for this session. Currently the session is listed as oral only, but a poster
session is also likely to be developed. The GSA abstract deadline is 3 June
2008.

Please forward this request to any colleagues that may be interested.

2. Lithospheric Structure and Geologic Evolution of the Gulf of Mexico Passive
Margin Geological Society of America 2008 Annual Meeting
5 - 9 October 2008
Houston, TX

Abstract deadline: June 3, 2008 Topical Session T64. Lithospheric Structure and Geologic Evolution
of the Gulf of Mexico Passive Margin (Organized by Libby Anthony, Steve Gao, and
Bob Stern)

Cosponsored by:
* GSA Geophysics Division
* GSA Structural Geology and Tectonics Division
* GSA South-central Division
* Gulf Coast Association of Geological Societies

Keynote speakers:
* Randy Keller - Geophysical evolution of the Gulf Coast.
* Tim Lawton - Tectonics of northeastern Mexico: salt diapers, mega-shear
accommodation and Cenozoic uplift
* Jim Pindell - The onshore-offshore evolution of the Gulf of Mexico.

Passive margins are hundreds of kilometers across and consist of
thick sedimentary sections built above broad transition zones that
separate oceanic and continental crusts and lithospheric mantles.
Link to EOS Forum article. Your interest in Texas and Gulf geology
would be a positive contribution to this session, and we urge you to
submit an abstract. Please also share this email with other
colleagues with similar interests. We hope to see you in Houston!

Libby Anthony, Steve Gao, and Bob Stern

Session description:

Only by studying passive margins can we understand how oceanic and
continental crust and lithosphere merge into each other, and what
controls the massive subsidence that allows many thousands of meters
of sediments to accumulate, such as underlies the 2008 meeting site
in Houston. The sedimentary section of passive margins harbors
most of the undiscovered hydrocarbon reserves and is the focus of
intense study, exploration, and drilling by oil companies. Passive
margins straddle the divide between continental and marine geology,
posing special challenges for academic scientists that wish to carry
out comprehensive studies. The nature of the underlying
transitional crust and lithosphere is much more poorly studied.
This session will focus on a wide range of issues related to the
geology and geophysics of the Gulf of Mexico. Furthermore,
the transportable seismometer array of NSF initiative "EarthScope"
is planned to traverse the continental part of the region beginning
in 2010 and this technical session will help prepare the community
to take advantage of the new that this deployment promises to
provide.

Workshop for Ocean Scientists (5/2/08)

To: Ocean Sciences Community
Re: Ocean Drilling Consortium
From: Manik Talwani, IODP-MI President/CEO
.................................................................................................................................................................
Funding is not available from government agencies for year-round operations on
the U.S.-sponsored IODP drillship. Funding is only available for an average of
seven months per year, from 2009-2013. The merits of utilizing the drillship
for the entire year are obvious, both for maintaining the scientific and
technical infrastructure on the ship and ashore, and for maintaining the scope
of scientific activities for the full year. You also may be aware of an avenue
that IODP-MI and the USIO have explored together over the last six months or
more, with a number of energy companies: an industry-sponsored ocean-drilling
program that would be funded by a consortium of energy companies and that would
utilize the JOIDES Resolution for an average of five months each year.

This initiative would not replace or displace IODP. Instead, it would provide an
independent program to support IODP and help maintain its viability.

To develop a proposal for an Ocean Drilling Consortium that would address
research challenges common to the academic community and industry, it was
proposed at a recent meeting attended by academic and industry representatives
that a workshop be held in June 2008. This workshop is planned for June 15-17
at Rice University in Houston, Texas. Support for the workshop will be provided
by several energy companies.

The workshop will be organized around three major themes:
I. Genesis and evolution of extensional margins and basin architecture
Extension/Hyperextension and denudation: volcanic versus magma-poor systems.

Understanding syn-rift and post-rift processes that control heat flow history
and effect
on source rock maturation.
Nature of outer highs, crustal type and origin.
Burial/subsidence history.
Processes of magma emplacement, extension, hydrothermal processes.
Sampling along strike transitions from volcanic-rich to volcanic-poor margins.
What is subsidence history of thin continental crust? Paleobathymetry.

II. De-risking uncertainty in shelf margin and deep water reservoirs
Architecture/connectivity of deep-water reservoirs and seals. What is the
distribution of
sands and shales,turbidite/source rock couplets?
Instrumentation experiments, including pressure connectivity.
Variability in seismic facies.
Variability in single depositional systems.
Processes and linkages from the shelf margin to the deep water environment.
How good are age constraints? Required for driving forces and rates of
processes (requires coring).
High quality/high resolution 3D seismic data needed for all of the above.
Pro-delta sources and how they are transported to deep water.

III. Distribution and genesis of Mesozoic through Paleogene marine source rocks
on passive margins
Define temporal and spatial limits with regard to global vs. local anoxic
events and productivity.
Forcing mechanisms, paleoclimate, paleoceanography, volcanic events, and
tectonic settings.
Productivity and preservation on the shelf vs. deep ocean (are they connected?)

Geology of source rocks,prediction of SRs in unknown areas.
- e.g. Indian Ocean
- Vagrant oils (comparative studies)

Participants will be divided into three working groups to address each theme.
Each group will be charged with developing specific objectives that can be
achieved by drilling. Each group should also consider the possibility of
high-scientific-value, single-site targets. These could include, for example,
areas with a lack of stratigraphic control and/or structural control, areas
where imaging is difficult (sub-basalt, sub-salt, etc.), or high-latitude/near
Arctic regions and other poorly sampled areas.

The main outcome of the workshop will be an outline of a proposal for a
four-year drilling program. This will include well defined targets that are
drillable within

Topical Session T73 - 2008 Geological Society of America Joint Annual Meeting (4/30/08)

Dear Colleagues -

We would like to draw your attention to the following topical session that may
be of interest to you at the upcoming 2008 Geological Society of America Joint
Annual Meeting. The meeting will be held October 5-9 in Houston, Texas.
Abstract submission deadline is June 3, 2008. More information about the
meeting can be found at https://www.acsmeetings.org/.

Topical Session T73:
Advances in Discontinuum Numerical Modeling in the Study of Earth Structure
and Deformation

Discontinuum numerical methods have been shown to reproduce complex material
rheologies and emergent structures at a wide range of scales, e.g., from
granular flow to large-scale tectonic evolution. The broad acceptance of
block- and particle-based numerical methods (e.g., DEM, SPH) and related
lattice based methods (e.g., LSM) has led to unique and creative applications
in geomechanics, rock and slope stability, fault and earthquake mechanics,
structural geology, volcanology, and many other fields. Hybrid
continuum-discontinuum methods also offer efficient tools for exploring
processes and properties of discontinuous materials. This session is designed
to showcase the range of applications of discontinuum numerical modeling to the
deformation and mechanical behavior of the Earth, and the insights gained
through them. We encourage submission of papers on a diverse range of topics,
including but not limited to (1) comparative numerical, lab, and/or field
studies, (2) numerical quantification and physical validation of material
properties and mechanical behavior, and (3) visualization of emergent
structures, properties, or evolution. We hope that this session will foster
discussion and exchange of new ideas and techniques, leading to further
advances in this promising numerical approach.

SEPM RESEARCH CONFERENCE 15-18 AUGUST 2008 (3/18/08)

SECOND CIRCULAR: SEPM RESEARCH CONFERENCE 15-18 AUGUST 2008

CLINOFORM SEDIMENTARY DEPOSITS: THE PROCESSES PRODUCING THEM AND THE
STRATIGRAPHY DEFINING THEM

ABSTRACT DEADLINE 31 MARCH 2008

Please submit to SEPM a 250-word abstract on topics related the
conference themes (see list below). The online submission form can be
found at:
http://www.sepm.org/activities/researchconferences/clinoform/clinoformhome.htm

We aim to bring together the modern, ancient and modeling communities
who have an interest in clinoform deposits, specifically in their
formation, character and significance. The focus will be on clinoforms
found on continental shelves, in association with fluvial-deltaic
systems,including the deeper shelf margin itself. Whereas the modern
community focuses on formative processes and spatial variability of
clinoforms, theancient community has data and insight on sedimentary
facies and development over longer time scales. The modelers (numerical
and experimental) are critical to both groups for providing links
between time scales. In turn, the modelers seek validation for the
results of their models. All three groups are interested in the
source-to-sink aspects of shelf-scale clinoforms. This conference will
allow prolonged dialog and discussion, while examining some classic
field examples of river- and wave-dominated deltas on shelf and
shelf-margin settings.

Conference Themes:
-Scale independence of clinoform morphology
-Linkages between deltaic and subaqueous shelf deposits
-Margin morphology and shelf-edge deltas
-Wave- and river-dominated deltas and relationships to clinoform structure
-Subaerial and subaqueous portions of deltas their formative
relationships
-Sandy and muddy gravity flows distributing sediment on clinoforms
-Along-clinoform heterogeneity of structure and the processes responsible
-Cross-shelf clinoform migration with changing sea level and supply

Special Session at AGU Joint Assembly meeting (3/3/08)

Please consider submitting an abstract to the following Special Session
at the AGU Joint Assembly Meeting in Ft. Lauderdale, FL. The abstract
deadline is March 5th, 2008:

Session V05: Linking Geophysical, Mineralogical, and Geochemical
Observations with Geodynamical Modeling of Subduction Systems

Conveners: Vlad Manea (UNAM), Chris Grose and Jeff Ryan (USF)

In recent years, significant progress has been made in the construction
of state-of-the-art geodynamic models of subduction zones. Our
understanding of the geochemical systematics of arc lavas, the
metamorphic and tectonophysical evolution of slabs, tomographic imaging
techniques, and other varied field observations and data analysis
methods at convergent plate margins have also experienced incredible growth.

The purpose of this session is to facilitate the collaborative
interpretation and corroboration of all sources of relevant data with
existing and future geodynamics models of subduction system structure
and evolution. We invite people from different fields connected with
subduction system evolution to contribute and discuss how to integrate
the available geophysical, mineralogical, petrologic, and geochemical
observations in order to better constrain subduction zone geodynamic
models.

Goldschmidt 2008: Physics and Chemistry of Thermochronology margins-list at nsf-margins.org (2/20/08)

Dear Colleagues,

Some of you may be interested in an upcoming session at the 2008 Goldschmidt
Conference in Vancouver, Canada, 13-18 July (abstract deadline is March 1).
Please forward this to anyone you think might also be interested:

Session 11a: The Physics and Chemistry of Thermochronology
David Shuster, Berkeley Geochronology Center and Ethan Baxter, Boston
University
Keynote: Kenneth Farley
Invited: Rodney Ewing
Invited: Thomas Zack

Interpreting the thermal histories of Earth and planetary processes through
radioisotopic chronometry requires an accurate understanding of the
fundamental physical and chemical mechanisms governing the behaviour of the
elements comprising thermochronometer behavior. Recent experimental and
theoretical advances have improved our ability to interpret some
thermochronometric systems, but important uncertainties remain in
understanding a variety of fundamental phenomena including critical aspects
of diffusion, exchange, and microstructures in minerals. This session will
highlight recent advances, limitations, and goals in understanding
phenomenological and mechanistic bases of thermochronology.
Contributions from experimental, field-based, and theoretical studies are
welcomed.

Goldschmidt 2008 - Session 09a (2/20/08)

Dear Colleagues,

I'd like to call your attention to the following Theme session at
Goldschmidt 2008.

Please consider submitting an abstract to this session!

Session 09a: Light element isotope insights into arc magmatism and
mantle dynamics

Convenors: Jeff Ryan, Yuji Sano

Keynote Speaker: Tobias Fischer

Discoveries arising from the isotopic and abundance systematics of low Z
elements (H, He, Li, Be, B, C, N, O, F, and Ne) have transformed our
understanding of subduction processes from the trench and deeper, and
the likely role that subduction has played in the evolution of the
Earth's mantle. This session seeks to highlight state-of-the-art
applications of light element and isotopic systems in addressing
questions at convergent plate boundaries and in studies of the mantle,
and frame these discoveries in the context of current geodynamic models
of plate convergence and subduction-zone magmatism. We also encourage
presentations addressing the apparent disconnects in our understanding
of the transport of H2O and H2O-mobile species through the subduction
cycle at specific plate boundaries, and globally.

Goldschmidt 2008: Crystal records of magmatic processes (2/18/08)

Colleagues,

With apologies for multiple postings I want to draw your attention to
a special session at the upcoming Goldschmidt 2008 meeting in
Vancouver. The abstract deadline is March 1.

Crystal records of magmatic processes

Crystal morphology and compositions provide important information
about the processes and rates of magma evolution along with sources
of crystals in magma. This session seeks to bring together
researchers who examine crystal records through studies of melt
inclusions, crystal textures and size distributions, phase
equilibria, chemical and isotopic compositions, diffusion modeling
and other relevant approaches. We are particularly interested in
studies that combine two or more of these techniques to provide
integrated histories of magmatic evolution and crystal heritage.

Goldschmidt Session - How are mantle heterogeneities (2/12/08)

Dear all,

We encourage you to submit abstract to the following session of the next Goldschmidt conference in Vancouver in July 2008.

Session 06b: How are mantle heterogeneities created? Convenors: Catherine Chauvel, Andreas Stracke
Keynote speaker: Cinzia Farnetani (IPGP Paris)
The Earth's mantle is chemically and isotopically heterogeneous as a result of internal differentiation and interaction with other major Earth reservoirs. Currently popular, though not universally accepted, hypotheses invoke inputs such as recycled oceanic lithosphere and associated sediments, foundered or eroded lower continental crust and lithosphere, or exchange of material with the outer core. This session welcomes contributions that constrain the chemistry, timing, and physics of formation and destruction of heterogeneities in the Earth mantle using a variety of methods from petrology, trace element and isotope geochemistry and numerical modeling.

Hoping to see you in Vancouver

ICDP Workshop on Testing the Extensional Detachment Paradigm (2/8/08)

ICDP Workshop on Testing the Extensional Detachment Paradigm:
A Borehole Observatory in the Sevier Desert Basin
(Basin and Range Province, Western United States)
July 15-18, 2008
Salt Lake City and Snowbird Mountain Conference Center, Utah, USA

Low-angle normal faults or detachments are widely regarded as playing an important role in crustal extension and the development of passive continental margins. However, no consensus exists on how to resolve the mechanical paradox implied by such faults or to account for the general absence of evidence for seismicity. Proposed drilling in the Sevier Desert basin in the western United States will test the extensional detachment paradigm 1) by making in situ measurements at depth of pore pressure, permeability, fluid chemistry, temperature and stress orientation and magnitude at a fault that is thought by most workers to have large normal-sense offset (< 47 km), to have been active over most of its history near its present 11° dip, and to be associated with contemporary surface extension; 2) by obtaining critical core of fault rocks at a down-dip site where offset should be large; and 3) by establishing more clearly the relationship between basin development, displacement along the interpreted fault, and footwall exhumation.

A workshop is being organized under the auspices of the International Continental Scientific Drilling Program (ICDP), to flesh out objectives, strategies and operational details of a research and drilling program, and to develop a consensus on the location of a drill site. The workshop will consist of a day in Salt Lake City, Utah, a day in the field in the Sevier Desert and adjacent Canyon Range, and two days at the Snowbird Mountain Conference Center. The principal product of the meeting will be a full drilling proposal, to be submitted to ICDP in January, 2009. A website has been established to provide information about the project as it develops: http://www.ldeo.columbia.edu/sevier/icdp/

We invite applications from the international community of interested scientists and engineers with pertinent expertise in borehole geophysics and instrumentation, drilling and coring techniques, structural geology, rock mechanics, reflection seismology, neotectonics/geodesy, stratigraphy, geochronology and geochemistry to participate in the workshop. Applications should be sent to Nicholas Christie-Blick (ncb@ldeo.columbia.edu; Lamont-Doherty Earth Observatory of Columbia University, Palisades, NY 10964-8000, USA) no later than February 15, 2008. Please provide complete contact information, a brief summary of your expertise, and your intended contribution to the project.

Decisions on participation will be made by the steering committee (N. Christie-Blick and M.H. Anders, Lamont-Doherty Earth Observatory, USA; G. Dresen, GeoForschungsZentrum Potsdam, Germany; G.S. Lister, Australian National University, Australia; G. Manatschal, Université Louis Pasteur, France; and B.P. Wernicke, California Institute of Technology, USA). Preference for participation and available travel funds will be given to those from ICDP member countries.

MARGINS Education Workshop (2/7/08)

“Bringing Source-to-Sink Discoveries to the Classroom” – a MARGINS Education workshop event at the AGU/ASLO Ocean Sciences Meeting

We would like to invite you to participate in an NSF-MARGINS workshop event entitled: “Bringing Source-to-Sink Discoveries to the Classroom.” This event is sponsored by the “MARGINS Data in the Classroom” project, which seeks to develop and test multidisciplinary geoscience learning materials based on the discoveries of MARGINS program research. Please take a look at the project website, http://serc.carleton.edu/margins, to find out more about this project, and see some of the educational products (MARGINS “Mini-Lessons”) that have been developed thus far.

The objectives of this event are to identify the key insights, discoveries and datasets arising from the MARGINS Source-to-Sink (S2S) Initiative, to inform and engage geoscience educators interested in sedimentary geology, and to encourage the development and/or contribution of S2S-related learning materials to the Mini-Lesson collection.

This event is conducted in association with the AGU/ASLO Ocean Sciences Meeting and will happen at the Rosen Plaza Hotel (the Ocean Sciences Meeting Headquarters hotel) on Monday, March 3rd, starting at 5:30 PM. A light dinner will be served. If you are interested in participating, please send an RSVP email to Dr. Jeffrey Ryan at ryan@cas.usf.edu, or contact him by phone at (813) 974-1598.

G-cubed theme: The Izu-Bonin-Mariana Subduction System: A Comprehensive Overview (2/1/08)

Hi all,

Please consider submitting your relevant research to the following special volume in G-cubed titled: The Izu-Bonin-Mariana Subduction System: A Comprehensive Overview. Deadline for submission is January 2010.

Theme description:
The Izu-Bonin-Mariana (IBM) subduction system, one of the NSF-MARGINS Subduction Factory Initiative focus sites, has received substantial attention from both the US and Japanese geoscience communities over the last 10 years. Large geophysical (swath bathymetry, gravity and magnetics, deep magnetotellurics, computer modeling, and broadband and multichannel passive and active seismics) and geochemical (magmatic volatiles, volcanic gas sampling, cross-chain dredge sampling, forearc drilling) studies have been carried out to investigate the full nature of this subduction system and its governing dynamics. Results from these experiments elucidate the detailed structure of the subduction system from the subducting Pacific Plate, across the forearc, arc, and backarc spreading centers and, for the first time, illuminate the dynamic processes that govern this and other subduction systems. Taken together, these studies provide one of the first comprehensive working models for active subduction and backarc spreading. This proposed G-Cubed Theme seeks to bring together the new and comprehensive geophysical and geochemical results from IBM, collected by US scientists (supported via NSF-MARGINS and other programs), and by Japanese geoscientists at IFREE, JAMSTEC, and other institutions.

STT-02 Structure and formation of rift basins and passive margins from surface to depth: Observations and modelling (Disciplinary Symposia, Structural Geology, Tectonics)

The formation of rifted continental margins by extension of continental lithosphere leading to seafloor spreading is a complex and still poorly understood component of the plate tectonic cycle. New observations and modelling allow us to investigate the underlying processes. Key questions that need to be resolved are factors that control the style of extension, the role of strain localisation and strain partitioning throughout the rift history, processes responsible for anomalous vertical motions during basin evolution such as phase changes or small scale convective instability of the mantle lithosphere, fundamental controls on the magmatic or a-magmatic nature of passive margins. For instance on volcanic margins the relative timing of extension and magmatism, the origin of excess magmatism during breakup, and its role for lithosphere rheology need further understanding. On magma-poor margins it is still unclear what controls the absence of magmatism. Also many rift basins appear to be characterized by anomalous subsidence patterns in the late syn-rift and post rift history. We encourage abstracts that offer new insights into large-scale crustal and lithospheric processes underlying rifting and passive margin formation as well as smaller scale studies of individual sedimentary basins, using constraints from observations and modeling

Mid-ocean ridges are the largest volcanic system on Earth and play an important role in the exchange of energy and material among various domains of our planet. Oceanic crust, covering over 65% of the Earth surface, is being generated at mid-ocean ridges. Submarine hydrothermal activities at mid-ocean ridges affect the chemistry of oceans and support a unique deep-sea ecosystem that is based on chemosynthesis rather than photosynthesis. Studies of mid-ocean-ridges are multidisciplinary in nature, encompassing disciplines of geology, geophysics, geochemistry, hydrothermalism, and biology. In recent years, several Asian countries including Japan, China, India, and Korea have started scientific programs to explore and investigate geological, hydrothermal, and biological processes at mid-ocean ridge and deep seafloor, while increasing collaborations with US and European counterparts under the auspices of InterRidge. Ophiolites, which are ancient oceanic crust exposed on land, have also attracted scientists in Asia as they offer important accessible sections of mid-ocean ridges. In this session, we invite scientific contributions on diverse issues related to mid-ocean ridges and ophiolites. In particular, we welcome new results and interpretations from recent sea-going cruises, fieldworks, and laboratory studies.

SE 73 Tectonic and magmatic evolution of western Pacific marginal basins Prof. Sang-Mook Lee (Seoul National University, Korea, South), smlee@snu.ac.kr

The western Pacific is host to numerous marginal basins many of which have formed as a result of change in motions of major plates during Cenozoic. These basins extend from Sea of Okhotsk and Sea of Japan (East Sea) to the north, South China Sea, basins in the Philippine Sea plate, active basins along Izu-Bonin Mariana trenches and Melanesian borderland, and down to the south along Tonga-Kermadec trenches. Many of these basins developed as a result of back-arc opening and have geologic structure and volcanic/magmatic manifestations, which are important sources of exchange in material and energy between deep earth and exterior including hydrosphere, atmosphere and biosphere. Understanding the formation and evolution of marginal basins has been a key question for geoscientists. The marginal basins are also of societal importance. The regions around the basins are among the most populated and industrialized places on the earth and are where we obtain much of resources including gas and petroleum. They are also regions venerable to natural hazards such as earthquakes and tsunamis. In recent decades many governmental agencies have been developing strategies to manage resources and mitigate possible hazards within their marine territories. While a lot of efforts including marine surveys are being conducted by individual countries, not much effort has been made to understand the geological phenomena that have shaped those basins which often require investigations far back into the past. In this session, we invite scientific contributions that have improved our knowledge of tectonic and magmatic events that have shaped the marginal basins. These include new survey results, measurements, modeling work and interpretations.

SE 74 Subduction Zone: Tectonics and Magmatism
Prof. Ryuichi Shinjo (University of the Ryukyus, Japan),
rshinjo@sci.u-ryukyu.ac.jp
Prof. Dapeng Zhao (Tohoku University, Japan), zhao@aob.geophys.tohoku.ac.jp
Trench-arc-backarc basin system represents one of major features of our planet earth. How are they initiated, how do they operate unique magmatism and seismic activity, and how do they eventually evolve? Understanding these systems is therefore by necessity a multidisciplinary effort. This session covers wide range of 'subduction zone'-related topics including geophysical, geochemical and petrological observations, modeling, and experimental results.
