Dear colleagues,

We would like to draw your attention to the session
DI009: Multidisciplinary constraints on the distribution of melt and volatiles and their roles through the subduction system
Please consider to submit an abstract by August 3rd, 23:59 EDT.

Session Description:
Subducting slabs transport geodynamically and geochemically significant quantities of volatiles to the Earth’s interior. A large portion of these materials returns to the surface/crust via volcanic arc and back-arc magmatism. The return flux involves processes from slab dehydration to hydration and melting of the mantle wedge to magma transport and eruption within the overriding plate. These processes are inherent to subduction zone dynamics and impact tectonic forces, and also critical for estimating Earth's water budget. Recent datasets, both onshore and offshore, and improved modeling capabilities provide opportunities to study the transport of melts/fluids/volatiles through the subduction system. We welcome stimulating contributions from all subdisciplines - field observations, laboratory results, and modeling - seeking to harness complementary constraints from multiple data types and to foster interdisciplinary collaboration. We particularly welcome studies using amphibious datasets that show the scientific potential of bridging the land/sea barrier.
