The National Science Foundation (NSF) Geosciences Program (CFDA 47.050) awarded a $185,953 project grant to the University of Texas at El Paso (UTEP) to conduct collaborative research on leveraging isotopic compositions of igneous systems to resolve the geometry and distribution of subducted sediment in the southern U.S. Cordillera. The project aims to determine the distribution and geometry of subducted sediment in the continental crust, using igneous rocks as a "deep-crustal probe" to identify the isotopic signature of the Orocopia Schist, a unique subducted sediment formation. This research will test end-member models for the structure of subducted sediment and provide training opportunities for two early-career researchers and five undergraduate students from historically marginalized and underrepresented groups. The award period runs from August 2024 through July 2026. No sub-awards are planned for this project.
