Dear Colleagues, Goldschmidt Conference, Vancouver, Canada, 13-18 July 2008 There will be a session focusing on the mechanisms and time scales of crustal assimilation in continental and oceanic settings at the upcoming Goldschmidt Conference to be held in Vancouver, Canada, July 13th-18th 2008 (http://www.goldschmidt2008.org). Abstract deadline - March 1, 2008 Session 10e: Mechanisms and time scales of crustal assimilation Convenors: David W. Peate & Michael Rowe (University of Iowa), Wendy Bohrson (Central Washington University) Exciting progress has been made recently in documenting the nature of interactions between mantle-derived mafic magmas and the overlying crust (continental and oceanic). Key advances have included development of quantitative models of assimilation, improved micro-analytical methods that allow measurement of elemental and isotopic variations within single crystals and melt inclusions, and new approaches for documenting assimilation time scales. For this symposium, we solicit submissions that illuminate the mechanisms and time scales of crustal assimilation through integrated geochemical and petrological studies. Contributions from the macro- to micro-scale are encouraged, including detailed stratigraphic studies that provide insight into the evolution of melt-crust interaction, quantitative elemental and isotopic modelling, in situ studies of crystals and melt inclusions, diffusion modelling, and kinetics of mineral dissolution. Examples from continental and oceanic settings are welcome. Keynote speaker will be John Wolff (Washington State University) ============================================================== 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. ==============================================================
