Dear friends,
We'd like to call your attention to Goldschmidt Session 8e: "The Eclogite – Arc Magma Connection: Linking Metamorphic and Igneous Processes at Subduction Zones".
Convenors: Maureen Feineman, Sarah Penniston-Dorland, Alicia Cruz-Uribe, Jeffrey Ryan
Keynotes: Richard Arculus (ANU) , Craig Manning (UCLA)
Arc lavas contain abundant evidence for the involvement of aqueous fluids in their production, and subduction-related metamorphic rocks from some localities show petrological and geochemical evidence for large fluxes of aqueous fluid. This session aims to link studies of fluid production by metamorphic reactions in and around the subducting slab to studies of fluid-mediated arc magma production in the mantle wedge. These two regimes are linked by fluid transport processes across the slab-mantle interface, which may themselves affect the composition of the fluid. We encourage contributions pertaining to fluid production and transport at metamorphic conditions, fluid transport in the mantle wedge, and slab-derived fluid contributions (volatiles, trace elements, isotope ratios) to arc magmas. We invite disciplinary and interdisciplinary submissions that use analytical, field, modeling, and experimental techniques to elucidate the processes of fluid production, transport, and evolution that ultimately lead to the generation of arc magmas.
The V.M. Goldschmidt Conference will be held in Knoxville, TN, USA, June 13-18, 2010.
The abstract submission deadline is February 21, 2010, 23:59 EST. Instructions can be found at http://www.goldschmidt2010.org/abstracts/instructions.
General information about the meeting, venue, and scientific program can be found at http://www.goldschmidt2010.org/index.
Hope to see you there!
Maureen, Sarah, Cici, and Jeff
