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...
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...
Pomona College received a $104,344 Project Grant award from the National Science Foundation Division of Earth Sciences on August 1, 2021 to complete work by July 31, 2024. The award supports collaborative research titled "Contribution of Mafic Magmatism to Upper Crustal Batholiths: A Case Study of the Sierra Nevada Batholith" under the NSF's Geosciences program (CFDA 47.050). The Geosciences program seeks to expand fundamental knowledge and understanding of the integrated Earth...
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 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...
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 $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 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $335,489 to Florida State University to conduct collaborative research on depth-dependent decarbonation processes in the Sierra Nevada, California. The research focuses on understanding how high-pressure, high-temperature metamorphism driven by magma intrusion into the Earth's crust can mobilize carbon and other elements, potentially leading to the formation of valuable skarn mineral...
This National Science Foundation (NSF) Division of Earth Sciences award, funded under the Geosciences program (CFDA 47.050) to support fundamental research to expand knowledge of the Earth system, provides $111,760 to Suffolk County Community College from September 1, 2023 to August 31, 2027. The funding will support a collaborative research project to integrate fluorspar dating and geophysical models to constrain the timing and mechanisms of the collapse of the Cordillera mountain range in...
Cornell University received a $348,300 Project Grant award from the National Science Foundation Division of Earth Sciences to investigate volatile evolution and decompression rates of high-intensity basaltic eruptions. Under the Geosciences program (CFDA 47.050), which supports basic research in integrated Earth system sciences, Cornell will conduct field and laboratory research over three years from July 2023 to June 2026. The university will analyze melt inclusions and reconstruct chemical...
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 characterize halogen movement and reservoirs in the deep earth, address uncertainties around whether halogens are enriched in plutonic magma chambers or erupted volcanic rocks, identify where halogens are hosted within the rocks, and assess the impact of halogens on magmatic processes and mineral deposits at volcanic arcs. Results from the research will significantly contribute to knowledge of bulk rock halogen compositions in continental arc crust.
