This Project Grant award from the National Science Foundation (NSF) Division of Earth Sciences under the Geosciences (CFDA 47.050) program provides $395,622 to the University of Washington to investigate how water moves through the subducting slab in eclogite facies subduction zones. The research aims to construct a plate-scale map of fluid pathways, including veins and ductile deformation zones, and link these pathways to specific dehydration reactions within the subducting oceanic crust and mantle. This work will leverage an exceptionally well-exposed subducted slab in the Italian Alps to integrate field mapping, petrological-geochemical analysis, and microstructural characterization. The findings will inform conceptual models of how water transport influences subduction zone hazards, such as volcanic eruptions and large earthquakes, as well as the broader geochemical cycling. The project will also engage four undergraduate students in hands-on research, providing paid opportunities to participate in fieldwork, data collection, and presentation of results.
