This $397,841 Project Grant awarded by the National Science Foundation's Geosciences Program (CFDA 47.050) will support research to study the process of subduction termination along the central California continental margin. The project will integrate offshore seismic tomography data with surface volcanic rock geochemistry to investigate the controversial "Isabella Anomaly", a high-velocity structure beneath California's Great Valley potentially associated with fragmented subducted Farallon plate. Key objectives include understanding how subduction terminates at spreading centers, assessing whether slab fragmentation is common during subduction cessation, and differentiating surface volcanism from various lithospheric sources. The research will be conducted by The University Corporation, a non-profit organization affiliated with California State University, Northridge, which has a track record of federal grant and contract awards to support STEM research and education, particularly for underrepresented groups. No sub-awards are planned under this grant.
