Dear All,
Please consider submitting and AGU abstract to session T051: The Varied Roles of Aqueous Fluids Near the Subduction Interface
Cross listed with Volcanology, Geochemistry and Petrology, Seismology and Mineral and Rock Physics
Invited speakers: Roland Burgmann (UC-Berkeley) and Emily Cooperdock (WHOI)
Session Description:
Along the subduction plate interface, water influences the rheological and geophysical properties as well as the rates and products of metamorphic reactions. Recent geologic and seismic studies demonstrate that strong feedbacks exist between the fluid-mediated chemical and petrologic evolution of the rock, deformation processes that control fault slip behavior, and geophysical signals we use to interpret physical conditions at depth. Fluid distribution and flux are thought to vary with depth and the permeability structure near the plate interface. These fluids are proposed to control episodic tremor-and-slip, dehydration-induced seismicity, serpentinization of the mantle wedge, overriding plate alteration, and the 4-D evolution in interface bulk-rock compositions, active deformation mechanisms, and rock strength. We invite contributions addressing the varied influence of aqueous fluids near the subduction interface from across the Earth science community including, but not limited to: experimental studies, geodynamics, petrology/geochemistry, structural geology, and geophysics.To unsubscribe from the GEO-TECTONICS list, click the following link:
