Colleagues
I draw your attention to two upcoming theme sessions at meetings in the
US in the next few months that I expect will be of interest to many of
you and for which the convenors seek contributions.

NE GSA 2001 (March 12-14, 2001; Burlington, Vermont, USA)
Theme Session 4: "Deformation, Metamorphism, and Melting:
Interactions in the Crust"
Convenors: Tracy Rushmer, Gayle Gleason and Michael Brown
The convenors of this session invite those interested in physical and
chemical evolution of the continental crust to contribute papers based on
recent results. Theoretical, field and experimental studies are all
welcome, and we encourage those in particular who are working in areas of
current interest in the community, such as the rheology of the
partially-molten crust, the geochemical and mechanical effects of melt in
the crust, and mechanisms of melt segregation, extraction, ascent and
emplacement.
Electronic abstract submission deadline December 5, 2000

Eleventh V.M. Goldschmidt Conference (May 20-24, 2001; Virginia,
USA)
Session title: "Crustal Melting: From Grain Boundaries to
Batholiths"
Convenors: Michael Brown and Robert J. Tracy
The aim of this session is to bring together geochemists and petrologists
to consider processes involved in, and the geochemical consequences of,
melt generation, segregation, ascent and emplacement in the crust during
orogenesis. These processes are investigated using fieldwork,
microscopy, geochemistry, experiments, numerical methods, and theory. The
geochemical consequences include crustal differentiation, the production
of a granulite lower crust, concentration of heat producing elements in
the upper crust and contamination of mantle-derived melts. Contributions,
both oral and poster, that address any aspect of this broad theme will be
welcome. We hope to arrange an informal field trip associated with this
theme session.
Electronic abstract submission deadline February 16, 2001
