[iris-bulk] Goldschmidt session: constraints on arc processes

[IRIS]

There will be a special session at the Goldschmidt meeting on  
"Seismic, geodynamic, and mineralogical constraints on arc and backarc  
processes".   The goal of the session is to draw together  
geophysicists, geodynamical modelers, petrologists and geochemists who  
are interested in arc and backarc processes.    The Goldschmidt  
meeting will be held from June 21-26 in Davos, Switzerland (http://www.goldschmidt2009.org 
).   The abstract deadline is February 22.

The session description is as follows:

session 6e   Seismic, Geodynamic, and Mineralogical Constraints on Arc  
and Backarc Processes
Convenors: Doug Wiens, Carmen Sanchez-Valle, Peter Ulmer
Keynote: Peter van Keken (University of Michigan)

Geodynamic models allow study of many important processes in  
subduction zones, including mantle flow patterns, magma production  
processes, and the cycling of material including volatiles through the  
system. Seismic observations provide important constraints on these  
models, but require experimental and computational results relating  
seismic observations to physical properties. In this interdisciplinary  
session, topics will include seismic studies of arc seismic structure  
and anisotropy, geodynamic models of arc processes, and theoretical  
and laboratory constraints on the relationship of seismic velocities,  
attenuation, and anisotropy to mantle temperature, mineralogy,  
deformation, and melt and volatile content.
