EarthRef.org Digital Archive (ERDA) -- GERM and MARGINS at the Fall AGU Meeting 2001

Description
Recent study has indicated that profound chemical alteration of subducting materials and related mass flux in fluids occur in forearc regions, beginning with diagenesis at extremely shallow levels, and continuing during prograde, high-P/T metamorphism and perhaps even partial melting of some lithologies in some subduction zones. In this session, we hope to address: fluid- flow and chemical alteration accompanying diagenesis during fluid expulsion in accretionary prisms; effects of prograde metamorphic devolatilization on the compositions of subducting materials and the production and mobility of metamorphic fluids; chemical processing in subducting slabs and sediments as recorded in serpentinite seamounts, mud volcanoes, and arc lavas (including across-arc suites); and the potential significance of forearc chemical alteration of subducting rocks for deep-mantle chemical heterogeneity

Project -- Meetings and Workshops -- Fall AGU Meetings
The Fall Meeting provides an opportunity for researchers, teachers, students, and consultants to review the latest issues affecting the Earth, the planets, and their environments in space. This meeting will cover topics in all areas of geophysical sciences.
