This $156,324 Project Grant, awarded by the National Science Foundation's Geosciences Program (CFDA 47.050), supports a collaborative research project at Occidental College to investigate the geometry and distribution of subducted sediment within the continental crust of the southern U.S. Cordillera. The project leverages the unique isotopic signatures of igneous rocks to map the subsurface location of the Pelona-Orocopia-Rand (Orocopia) schist, which represents subducted and accreted sediment. This research aims to improve understanding of how the incorporation of subducted sediment into the continental lithosphere can impact tectonic deformation, seismic activity, and the distribution of critical minerals. The grant also provides research opportunities for two early-career scientists and five undergraduate students from underrepresented groups at Occidental College and another university. No sub-awards are planned under this grant.
