The National Science Foundation (NSF) Division of Earth Sciences awarded a 3-year, $347,913 Project Grant to Northern Arizona University (NAU) to investigate fluid infiltration of the continental crust during Laramide flat-slab subduction, an ancient tectonic setting. The research aims to improve mathematical simulations of similar modern tectonic settings that pose seismic risks to human populations. The project supports the participation of undergraduates and four early career PhDs, three of...
This three-year, $393,948 project grant from the National Science Foundation's Geosciences program (CFDA 47.050) will fund research to resolve conflicting tectonic models for the Laramide orogeny and flat-slab subduction in southern California. The grantee, the University Corporation at California State University, Northridge, will support field work and laboratory analyses in the San Gabriel Mountains to better understand the timing and driving forces behind mountain building in the western...
The National Science Foundation awarded the University of Vermont & State Agricultural College a three-year, $288,924 Project Grant under the Geosciences program (CFDA 47.050) to conduct collaborative research resolving conflicting tectonic models for the Laramide orogeny and flat-slab subduction in southern California. The University will perform three field seasons of data collection in the San Gabriel Mountains, along with geochronology, geochemistry, and microstructural laboratory...
This $550,014 Project Grant from the National Science Foundation Division of Earth Sciences, under the Geosciences federal grant program (CFDA 47.050), will fund research at Arizona State University to advance understanding of the influence of subducted slabs on thermal and chemical heterogeneities in Earth's lowermost mantle. The awardee will perform high-resolution thermo-chemical modeling using supercomputing to simulate the variable behaviors and interactions of subducted tectonic plates...
The National Science Foundation (NSF) has awarded a $397,841 Project Grant under the Geosciences program (CFDA 47.050) to The University Corporation at California State University, Northridge. The grant will fund a 2-year project to study the process of subduction termination along the central California continental margin. The project will use new offshore and onshore seismic data, along with geochemical analysis of surface volcanic rocks, to investigate the controversial "Isabella...
This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $164,486 to the University of Alabama to conduct collaborative research evaluating tectonic models for the western U.S. Cordillera through the metamorphic history of the Pelona-Orocopia-Rand schists. The research aims to test the viability of the flat slab subduction model against alternative hypotheses, including terrane collision, by determining the age, pressure, and temperature recorded...
This $393,670 National Science Foundation award under the Geosciences program (CFDA 47.050) funds research at the University of California, Davis from March 2022 through February 2025 to test the role of metastable olivine in subduction dynamics and deep earthquakes. The researchers will use state-of-the-art numerical simulations integrating experimental and observational parameters to model various subduction scenarios with and without the presence of metastable olivine. They will compare model...
This $544,307 federal Project Grant award, funded by the National Science Foundation's (NSF) Geosciences program (CFDA 47.050), supports a collaborative research project investigating seismic cycle processes in the earthquake critical zone of major continental strike-slip faults. The research team, led by Utah State University (USU), will bridge geoscience and engineering concepts, data, and models to deliver research products and broader impacts across six key pathways: Establishing a...
This National Science Foundation Geosciences Program (CFDA 47.050) Project Grant award of $354,304 provides funding for a collaborative research project titled "Designing Sedimentation and Tectonics Research Experiences for Student Success (DE-STRESS)" from September 1, 2025 to August 31, 2028. The project is a joint effort between California State University San Bernardino and the University of Cincinnati to recruit junior-level university students and sophomore-level community...
This $156,324 federal Project Grant award from the National Science Foundation's Geosciences program (CFDA 47.050) supports research to determine the distribution and geometry of subducted sediment in the continental crust of the Southern U.S. Cordillera. The primary focus is on testing models of uniform, sheet-like sediment layers versus non-uniform, diapir-like sediment bodies within the crust. The research uses the unique isotopic signature of the Pelona-Orocopia-Rand Schist, exposed in...
