Information - TS2 Tectonics and fluid flow at subduction zones
Event Information
The interplay between fluids and active tectonics at subduction zones greatly influences a wide range of phenomena. Oceanic plates may be strongly hydrated by water percolation during bending-related faulting at the trench. Fluids are transported in the underthrusted plate in subducting sediment, oceanic crust and slab mantle. Fluids are progressively released at a broad range of depths during early compaction and diagenesis and subsequent metamorphism. Fluids escaping from the subducting plate underneath the forearc influence the cycle of interplate earthquakes, and processes of sediment accretion/underplating and tectonic erosion. Fluids traversing the faulted overriding plate seep at the seafloor chemically linking lithosphere and hydrosphere and give rise to chemosynthetic communities. Deeper in the subduction zone fluid release may be linked to intraslab earthquakes and promote melting in the mantle wedge.
This session aims at gathering a multidisciplinary set of presentations from different disciplines related to the study tectonics and fluids at subduction zones. We encourage submission of abstracts presenting data and models based on geophysical, geological, geochemical, experimental and numerical methods.
