This $330,935 project grant awarded by the National Science Foundation (NSF) Division of Earth Sciences under the Geosciences program (CFDA 47.050) supports collaborative research to quantify how halogens (F, Cl, Br, I) and chlorine isotopes behave during metamorphic dehydration of sedimentary rocks. The research team at the University of California, Santa Barbara (UCSB) will analyze halogen concentrations and chlorine isotopes in well-characterized metapelite rock suites from around the world...
This Project Grant award from the National Science Foundation (NSF) Geosciences program (CFDA 47.050) provides $291,557 to Brown University to conduct collaborative research on the behavior of halogen elements (fluorine, chlorine, bromine, and iodine) in continental volcanic arc systems. The key objectives are to: Determine whether halogens are concentrated more in plutonic or volcanic rocks within the same ancient arc system exposed in the Sierra Nevada, California. Identify the primary mineral...
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 $254,882 project grant from the National Science Foundation's Geosciences program (CFDA 47.050) supports research investigating the sensitivity of reactive halogen abundance to glacial-interglacial climate change. Over a three-year period ending June 2025, the University of Rochester will examine how blowing snow on sea ice may explain increased sodium ion observations in ice cores over glacial-interglacial timescales. The project will also identify major drivers for reactive halogen...
The National Science Foundation Division of Earth Sciences awarded Pomona College a $114,019 Project Grant under the Geosciences federal grant program (CFDA 47.050) to conduct collaborative research on halogen behavior in the pluton-to-volcanic arc system from August 15, 2022 to July 31, 2025. The research will measure halogen concentrations in intrusive plutonic rocks and extrusive volcanic rocks from the same ancient arc system now exposed in the Sierra Nevada, California. This will help...
The National Science Foundation awarded a $149,580 Project Grant to the University of Texas at Austin under the Geosciences program (CFDA 47.050) to conduct collaborative research on halogen behavior in the pluton-to-volcanic arc system. Over a three year period ending July 2025, researchers will measure halogen concentrations in intrusive and extrusive rock samples from the Sierra Nevada arc to characterize halogen composition and behavior within the arc magmatic system. Specific products...
This three-year, four-hundred twelve thousand nine hundred forty-three dollar Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) will support collaborative research to experimentally simulate zircon recrystallization processes in aqueous solutions. Vanderbilt University will conduct innovative isotope tracer experiments on zircon-fluid mixtures at high pressures and temperatures, characterizing materials using microanalysis techniques. Researchers aim to...
The National Science Foundation (NSF) Division of Earth Sciences awarded a $615,305 Project Grant entitled "GEO-CM: PROSPECTING FOR CRITICAL ELEMENT DEPOSITS: AN INTERDISCIPLINARY APPROACH USING EXPERIMENTAL GEOCHEMISTRY AND FIELD-INFORMED MODELING OF SEDIMENT TRANSPORT" to the University of Rochester. The grant aims to develop new tools and methods to help geoscientists locate undiscovered deposits of critical minerals, such as cobalt, niobium, and tin, that are essential for...
This $330,221 federal Project Grant award was made by the National Science Foundation's Geosciences Program (CFDA 47.050) to the President and Fellows of Harvard College (Harvard University) to support research on the habitability of the Hadean Earth. The project aims to analyze Hadean zircons recently discovered in South Africa to better understand Earth's early history, including the onset of plate tectonics, mantle outgassing, and the emergence of the first continental crust. The research...
This Project Grant award from the National Science Foundation (NSF) Division of Earth Sciences (CFDA 47.050 - Geosciences) supports collaborative research by Trustees of Union College in Schenectady, NY to study diffusion behavior of elements in the minerals zircon and baddeleyite. The $118,795 award, active from September 1, 2023 to August 31, 2026, will fund experiments to better understand how atoms diffuse within these important geochronometric minerals. The findings will help improve...
This three-year National Science Foundation project grant of $358,891 will fund research and educational activities related to understanding the cycling of halogens like chlorine and fluorine in Earth's early magmas and fluids. Led by the University of Rochester under the Geosciences program (CFDA 47.050), the project aims to advance fundamental knowledge of integrated Earth system processes through targeted studies of ancient zircon minerals. Key deliverables include high-temperature and high-pressure laboratory experiments to determine halogen partitioning behaviors between zircon-melt and zircon-fluid systems over Earth's first 4 billion years. Researchers will also conduct halogen analysis of archean and hadean-era zircons to explore early crust-hydrosphere cycling models. Educational activities will involve training a PhD student in relevant techniques and offering an advanced geochemistry course, plus a senior thesis project for an undergraduate student. Findings seek to refine understanding of halogen mobility and early crust/mantle/seawater interactions critical to Earth evolution models.
