[margins-list] Another special session at 2009 Goldschmidt Conference

[margins-list at nsf-margins.org]

Dear Colleagues,

We would like to call your attention to another special session  
related to subduction zone processes at the 2009 Goldschmidt  
Conference in Davos, Switzerland, entitled, "Volatiles in subduction  
zone magmas, from the slab to the surface." The abstract submission  
deadline is 22 February, 2009, and full details can be found at  
http://www.goldschmidt2009.org

Session 06a: Volatiles in subduction zone magmas, from the slab to  
the surface

Conveners:
Katherine Kelley, GSO/Univ. of Rhode Island, USA
Roberto Moretti, Istituto Nazionale di Geofisica e Vulcanologia, ITALY

Description:
Volatiles play a central role at subduction zones, influencing  
processes as varied as mantle melting, element transport,  
crystallization, magma migration and degassing. The impact and inter- 
relationships of volatile elements and species (e.g., H2O, CO2, S  
species, Cl, F, etc.) in subduction zone slab, mantle, and magmatic  
systems are essential components of this complex tectonic setting,  
and this session aims to present a comprehensive portrait of the  
current state of volatile studies at all levels through the  
subduction zone. This session welcomes all contributions from theory,  
models, experiments and measurements about the volatile cycle from  
the slab to the surface, including slab devolatilization, volatile  
fluxes and geochemical budgets, volatile solubility and physico- 
chemical properties of melts and HT fluids, melting and metasomatic  
processes, and pre- to syn-eruptive magma conditions as recorded by  
melt inclusions and phase equilibria.

Keynote speaker:
Nicole Metrich, Laboratoire Pierre Süe, CNRS-CEA, FRANCE
