Project Grant 2615315
- The National Science Foundation Division of Earth Sciences awarded Carnegie Institution of Washington $224,419 on September 1, 2026, under the Geosciences program (CFDA 47.050) to establish high-precision eruptive chronology for the Caribbean Large Igneous Province and determine its relationship to oceanic anoxic events. The project combines chemical abrasion–isotope dilution–thermal ionization mass spectrometry (CA-ID-TIMS) U-Pb zircon geochronology with re-osmium isotope stratigraphy,...
- The National Science Foundation Office of Integrative Activities awarded Texas A&M University $874,116 on March 15, 2026, to acquire a thermal-ionization mass spectrometer (TIMS) under the Integrative Activities program (CFDA 47.083). The TIMS will enable high-precision measurements of osmium and other isotopic systems in geologic and biogenic materials, supporting research into ocean anoxic events, hydrothermal fluid evolution, continental weathering, and the environmental effects of...
- The National Science Foundation Division of Earth Sciences awarded Texas A&M University $427,960 on August 1, 2026, under the Geosciences program to conduct laboratory heating experiments and computational modeling that advance clumped-isotope thermometry of carbonate minerals. Clumped-isotope thermometry reconstructs ancient ocean temperatures and tracks thermal evolution in petroleum reservoirs and ore deposits, but accuracy is limited by incomplete understanding of how heat during...
- The National Science Foundation Division of Ocean Sciences awarded Oregon State University $499,008 for a Project Grant on March 15, 2026, under the Geosciences program (CFDA 47.050). The project conducts high-resolution 40Ar/39Ar age-determination experiments on lava samples from the Manihiki and Hikurangi plateaus to establish the timing and duration of their emplacement and test whether eruptions from Ontong Java Nui, a massive large igneous province, coincided with and potentially caused...
- The National Science Foundation Division of Earth Sciences awarded the Smithsonian Institution $354,472 on August 1, 2026, to conduct collaborative research on magma sources and formation through high-pressure and high-temperature laboratory experiments and mathematical modeling. The recipient will use electron microprobe and X-ray absorption near-edge structure (XANES) analyses to measure the oxidation state of iron in peridotite samples and examine how oxygen fugacity varies between...
- This Project Grant award of $463,475.00 from the National Science Foundation's Geosciences Program (CFDA 47.050) supports research to investigate calcium isotope variations in ocean island basalts (OIBs) to better understand the deep Earth carbon cycle. The research aims to distinguish mantle source heterogeneity from magmatic processes that control calcium isotope signatures in OIBs. Key objectives include tuning phase equilibrium models to constrain magmatic processes, mantle source...
- The National Science Foundation Division of Earth Sciences awarded Rutgers, The State University $499,665 on August 1, 2026, under the Geosciences program (CFDA 47.050) to provide logistical support and core analysis for the Paleogene Earth Perturbations, US Atlantic Coastal Plain (PEP-US) scientific drilling initiative. The project recovers and analyzes marine sediment cores from ten sites (19 coreholes) across the US Mid-Atlantic Coastal Plain in New Jersey, Delaware, and Virginia to study the...
- This $109,466 Project Grant from the National Science Foundation Division of Earth Sciences, under the Geosciences federal grant program (CFDA 47.050), will fund collaborative research between the University of Texas at El Paso and researchers in Ecuador. The research aims to provide insights into the geologic processes and hazards along ocean-continent subduction plate boundaries through an integrated study of sedimentary basins and magmatism records across Ecuador. Researchers will employ...
- This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will fund collaborative research to develop an integrated framework for understanding the Late Devonian mass extinctions and associated changes in ocean chemistry and climate. The $231,421 award to Texas A&M University aims to: Establish a new geologic framework linking Late Devonian mass extinctions to the formation of epeiric black shale deposits across North and South America using...
- This $185,953 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports collaborative research to leverage isotopic compositions of igneous systems to resolve the geometry and distribution of subducted sediment in the southern U.S. Cordillera. The research, led by the University of Texas at El Paso, aims to determine the distribution and geometry of subducted sediment in the continental crust by using igneous rocks as "deep-crustal probes" to...
The National Science Foundation Division of Earth Sciences awarded Texas A&M University $472,945 on September 1, 2026, under the Geosciences program (CFDA 47.050) to establish high-precision eruptive chronology for the Caribbean Large Igneous Province. The recipient will combine chemical abrasion–isotope dilution–thermal ionization mass spectrometry U-Pb zircon geochronology with Re-Os isotope stratigraphy, platinum-group element geochemistry, zircon trace-element chemistry, and Hf isotope analysis to constrain the timing, duration, and eruptive rates of Caribbean LIP volcanism. The research encompasses U-Pb dating of volcanic units including ash layers interbedded with ocean drilling cores and Colombian field sections. Re-Os isotope and platinum-group element analysis of associated sediments will track volcanic inputs and the development of marine anoxia. The integrated framework will test whether Caribbean LIP volcanism directly drove global carbon cycle perturbations associated with oceanic anoxic event 2 or exerted stronger influence during oceanic anoxic event 3, and will distinguish mantle plume from arc-related magmatic sources to provide insight into the tectonic evolution of the region. Performance extends from September 1, 2026, through August 31, 2029, with work performed in College Station, Texas.
