State-of-the-Arc: Questions and Progress about the Subduction Zone Factory
State-of-the-Arc: Questions and Progress about the Subduction Zone Factory
Session ID#: 280119
Session Description:
Subduction of oceanic lithosphere into Earth’s interior is a fundamental process that drives some of the most significant natural hazards, including large earthquakes, explosive volcanism, tsunamis, and long-term climate variability. Despite major advances, key questions remain regarding the physical and chemical processes governing subduction zone dynamics. Outstanding questions include, but are not limited to, the role of fluid–rock interactions in generating slab and interface seismicity; the mechanisms and pathways of mass and volatile transfer from the subducting slab to the mantle wedge and their links to arc magmatism; controls on the spatial and temporal evolution of coupling and thermal structure along the plate interface; and the ultimate fate of subducted slabs and their volatile cargo in the deep mantle. This session invites contributions spanning geophysics, geodynamics, petrology, geochemistry, and experimental and numerical modeling to advance our understanding of subduction systems. Interdisciplinary contributions are especially encouraged.
