****************************************************** From: Cyril Aubaud <aubaud@xxxxxxxxxxxxxxx> ****************************************************** Dear Colleagues, We would like to encourage you to contribute an abstract to the following interdisciplinary session, planned for the Fall AGU, 2007. The abstract submission deadline is September 6, 2007. DI02: Volatiles and Melts in the Earth's Interior Sponsor: Study of Earth's Deep Interior (DI) Cosponsor: Mineral and Rock Physics (MRP), Tectonophysics (T), Volcanology, Geochemistry, and Petrology (VGP) Description: Volatiles and melts in Earth's deep interior play a key role in the dynamics and evolution of the planet. Volatiles such as hydrogen, carbon, and sulfur, stored in various forms and concentrations, are known to have significant effect on the generation of partial melts. Extraction or impregnation of partial melts in turn can deplete or enrich the mantle in volatiles and aid major and trace element differentiation. The presence of volatiles and melts are also known to influence the rheology and seismic properties of minerals, and likely have considerable influence on convective processes in the mantle. This session seeks to bring together recent advances in geochemical, geophysical, and petrologic constraints on the origin, stability, characterization, and detection of volatiles and volatile-bearing melts in the mantle and on the physico-chemical consequence of the presence of fluids and melts in the mantle processes and properties. We encourage contributions based on natural observations, experimental determinations, and theoretical calculations, from any discipline, that touch on any aspect of melting and volatile cycling in the Earth's interior. http://www.agu.org/meetings/fm07/?content=search&show=detail&sessid=60 Convener: Rajdeep Dasgupta (LDEO, Columbia University; rajdeep@xxxxxxxxxxxxxxxxx) Garrett Leahy (Yale University; Garrett.Leahy@xxxxxxxx) Cyril Aubaud (IPGP; aubaud@xxxxxxxxxxxxxxx) Jackie Dixon (University of Miami; jdixon@xxxxxxxxxxxxxxxxx) (apologies for cross-postings) ---------------------------------------------- Cyril Aubaud Institut de Physique du Globe de Paris Laboratoire de Geochimie des Isotopes Stables 2 place Jussieu 75005 Paris - France Phone : +33 1 44 27 68 74 Fax : +33 1 44 27 28 30 ============================================================== To unsubscribe from the volcano list, send the message: signoff volcano to: listserv@xxxxxxx, or write to: volcano-request@xxxxxxxx To contribute to the volcano list, send your message to: volcano@xxxxxxxx Please do not send attachments. ==============================================================
