Dear Colleagues,

We encourage you to submit an abstract to the Union session U32 "Physical
and Chemical State of Subducting Slabs and the Slab-Mantle Interface:
Forearc, Subarc, and Beyond" at the Fall AGU meeting this December in San
Francisco. We're very excited about the interdisciplinary nature of this
session.

The Fall AGU meeting takes place from December 5-9 this year in San
Francisco. Please see the meeting website
http://sites.agu.org/fallmeeting/ for details about the meeting. Abstracts
must be submitted by August 4 at http://agu-fm11.abstractcentral.com/ .

U32 "Physical and Chemical State of Subducting Slabs and the Slab-Mantle
Interface: Forearc, Subarc, and Beyond"
We will consider the state of subducting slabs and the "subduction
channel" by merging perspectives from structural, geophysical, petrologic,
geochemical, experimental, and theoretical studies. Topics could include:
linkage between earthquakes and metamorphism and deformation; relationship
between devolatilization and silent earthquakes; subduction accretion and
erosion and cycling of continental crust; evolving subduction channels and
exhumation of HP and UHP metamorphic rocks; element mobility and processes
of mass transfer; devolatilization histories and deep-Earth volatile
cycling; physical and chemical properties, and transport of
subduction-zone fluids; mechanisms by which fluids enter and alter mantle
wedges.

Invited speakers:
Pascal Audet, University of California, Berkeley
Ethan Baxter, Boston University
Peter van Keken, University of Michigan
Ikuko Wada, Woods Hole Oceanographic Institute
