| Abstract |
This project involves a geophysical study of the northern Red
Sea where the rift terminates into the sinistral Dead Sea transform
and a slow spreading zone in the gulf of Suez. This area is a good
natural laboratory for testing plate driven asthenospheric flow
vs. bouyancy driven asthenospheric flow during continental rifting.
The relative importance of each of these processes is to be evaluated
from a combination of surface manifestations (topography, geologic
history, subsidence history of basins) and probing of the deep structure
with a passive seismic array. The seismic array, in turn, has two
parts: a basic crustal structure component to determine basic geometry
and a shear wave splitting component to look at mantle flow. The
results of these studies will be combined with modeling studies
(flexural modeling of rift flanks and mantle flow models) to develop
a synthesis of the geodynamics. *** |
