The subduction of oceanic lithosphere into Earth’s interior is a fundamental geodynamic process responsible for the formation of tertiary crust on Earth, transport of surface materials into the deep interior and vice versa, as well as some of the most catastrophic natural events, including explosive volcanic eruptions, large-magnitude earthquakes and associated tsunamis. Despite significant progress in research over the past few decades, critical questions remain—including the mechanisms of slab-to-mantle material transport and chemical geodynamics, the role of fluid-rock interactions in slab seismicity, the controls on the decoupling–coupling transition and thermal structure at the plate interface, and the ultimate fate of subducting slabs and their volatile cargo. This session aims to bring together expertise from petrology, geochemistry, experimental laboratory studies, geophysics, and geodynamics, to advance our understanding of subduction zone dynamics. Interdisciplinary contributions are especially encouraged.
