This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a collaborative research project to study the tectonic uplift history of the northern Sierra Nevada mountain range in California. The $304,910 award, effective August 15, 2024, will fund the use of low-temperature thermochronology and analysis of ancient river deposits to reconcile conflicting models of the Sierra Nevada's geological development. The research involves researchers from...
This $190,957 collaborative research project awarded by the National Science Foundation's Geosciences Program (CFDA 47.050) aims to investigate the tectonic uplift history of the northern Sierra Nevada mountain range in Eastern California. The project will use low-temperature thermochronology and analysis of ancient river sediments to reconcile conflicting models about the timing and causes of the Sierra Nevada's topographic development. Researchers from three universities will mentor...
This three-year, $337,782 Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) supports research at California State University Fullerton and Princeton University to determine the time and length scales of magma bodies in magmatic arcs. The grant recipients will study potassium feldspar phenocrysts and megacrysts up to 12 cm long containing mineral inclusions from the Tuolumne Intrusive Complex in Yosemite National Park. Electron microprobe, laser...
This $386,491 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports collaborative research to reconcile discrepancies in the uplift history and tectonic causes of the northern Sierra Nevada mountain range in eastern California. The research will use low-temperature thermochronology and analysis of ancient river deposits to constrain the exhumation history and topographic evolution of the northern Sierra Nevada. The project aims to determine whether...
This two-year, $274,138 National Science Foundation project grant supports research into crustal evolution and recycling processes in a long-lived magmatic system exposed in the Transverse Ranges of California. Funded under the NSF's Geosciences program (CFDA 47.050), the project aims to advance understanding of continental arc growth through quantitative analysis of field and laboratory data from diverse rock samples representing different depths and time periods within the magmatic system....
This $198,248 Project Grant award from the National Science Foundation's (NSF) Geosciences Program (CFDA 47.050) will support research to investigate the magmatic evolution and timing of the Independence Dike Swarm in eastern California. The principal objectives are to: 1) characterize the chemical composition and age of dikes across the swarm, including segments that are only tentatively correlated, to better understand the magmatic processes and emplacement history; 2) develop a dating...
This National Science Foundation (NSF) Project Grant under the Geosciences Program (CFDA 47.050) provides $185,478.00 in funding to Northern Illinois University (NIU) to evaluate tectonic models for the western United States Cordillera region through a detailed study of the Pelona-Orocopia-Rand schist. The researchers will use modern analytical techniques, including Raman spectroscopy, bulk chemical analysis, and pressure-temperature modeling, to determine the age, pressure, and temperature...
This Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) provides $180,000 to Harvard University from September 1, 2022 to August 31, 2024. The funding will support research analyzing zircon samples from the Wyoming Province and Singhbhum Craton dating back 4.01 billion years or more to better understand early Earth processes, including evidence for plate tectonics, the distribution of surface water, and rock types. Specifically, the grantee will conduct...
This $102,488 federal Project Grant award from the National Science Foundation's (NSF) Geosciences Program (CFDA 47.050) supports a collaborative research project to study the stable isotopic composition of zirconium in the ocean. The award was made to the California Institute of Technology (Caltech) and will run from September 1, 2024 to August 31, 2027. The key objectives of this research project are to: (1) determine the stable zirconium isotopic composition of various ocean reservoirs,...
This Project Grant award of $291,976 from the National Science Foundation's Geosciences Program (CFDA 47.050) will support field research and laboratory studies in central Chile to test competing tectonic models for the Mesozoic evolution of the South American margin. The research aims to determine if the Andes formed through continuous East-dipping subduction or the accretion of an intra-oceanic island arc. Key activities include using igneous zircon U-Pb geochronology, trace element and...
