*********************************************************** From: Fidel Costa <fcosta@xxxxxxxxxxx> *********************************************************** Dear All, we would like to draw your attention to the session: ''V38: Minerals, Inclusions and Volcanic Processes: Crystal-scale records of magma dynamics'' which will happen at the AGU, in San Francisco 15 – 19 December 2008. Abstract deadline is 10th of September 2008. Please see description of the session below. We hope to see you all there! best regards, Mary Reid Northern Arizona University Department of Geology Flagstaff, AZ, USA 86011 928-523-7200 mary.reid@xxxxxxx Kari Cooper U.C.

Building from the theme of a pre-meeting RiMG shortcourse, the goal of this session is to bring together scientists who use different methods to understand how information about magma dynamics can be extracted from the crystal record and in particular to explore how crystal records can be used to distinguish crystals and crystal populations in the same magmas that may record different histories. We are interested in contributions from those who date mineral aggregates and individual crystals and estimate residence times from U-series disequilibria and diffusion profiles, use isotopes to identify magma batches and processes, and use crystal chemistry, imaging, and isotopes to evaluate open system processing and untangle the evolution of co-mingled (autocrysts/phenocrysts, antecrysts, xenocrysts) crystals. We are especially interested in submissions that combine multiple techniques to address the sometimes disparate origins of crystals in magmas. ============================================================== 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. ==============================================================
