The National Science Foundation (NSF) awarded a $385,643 project grant under the Geosciences program (CFDA 47.050) to the University of Vermont & State Agricultural College to investigate magma diversification and mobilization processes in the lower continental crust. The 3-year research project will link field mapping, microstructural analysis, geochemistry, and geochronology to test competing models for how magmas form and are extracted from the deep roots of continental arcs. The...
This Project Grant award of $177,497 from the National Science Foundation's Geosciences Program (CFDA 47.050) supports collaborative research by the University of South Florida to unravel the timing and episodicity of magmatic intrusions under a distributed volcanic field in the western United States. The key research activities include: (1) constraining the absolute and relative ages of intrusive episodes to calculate the number and rate of intrusive events; (2) locating and estimating the...
This $355,607 Project Grant award from the National Science Foundation (NSF) Division of Earth Sciences under the Geosciences program (CFDA 47.050) supports collaborative research to investigate an ancient example of flat-slab subduction in southern California and western Arizona. The goal is to collect data from rocks that were once located above the descending oceanic plate in order to improve simulations and understanding of similar modern tectonic settings, many of which pose significant...
This Project Grant award from the National Science Foundation's (NSF) Geosciences Program (CFDA 47.050) will provide $343,410 to The Pennsylvania State University (Penn State) for a postdoctoral research project investigating how sedimentary rocks are incorporated into the Earth's lower continental crust. The project aims to improve understanding of lower crustal formation processes and contribute to training the next generation of Earth science researchers. Key activities include field mapping,...
The National Science Foundation awarded a $174,000 two-year Project Grant to researchers at the University of Colorado Boulder under the Geosciences program (CFDA 47.050). The grant will fund a research project to Quantify Scale of Lower Crust and Mantle Heterogeneities Beneath the Continental United States through Bridging Seismology, Mineral Physics, Petrology, and Magnetotellurics. The Geosciences program supports basic research to strengthen understanding of Earth's integrated system. This...
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 $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...
This $228,331 National Science Foundation project grant supports collaborative research to understand the evolution of continental lithosphere beneath New England through geologic time. Funded under the Geosciences program (CFDA 47.050), the research team will employ seismic imaging techniques and analyze geologic structures exposed at the surface to illuminate plate tectonic processes that have shaped the region. Specifically, the investigators from the University of Vermont and partner...
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 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will provide $190,501 to Colgate University to conduct collaborative research on advances in African crust and upper mantle dynamics. The research aims to improve understanding of plate tectonics and Earth's dynamic interior by investigating how the African continent interacts with the underlying convecting mantle. Key objectives include developing high-resolution models of the kinematics,...
This Project Grant award from the National Science Foundation (NSF) Division of Earth Sciences, funded under the Geosciences CFDA program (47.050), provides $129,643 to the University of Arkansas, Fayetteville (UA) to conduct collaborative research on the impact of magmatic underplating on the evolution of the lower continental crust. The key objectives are to: (i) constrain the timing and duration of magmatic intraplating and metamorphism in different tectonic settings, (ii) identify and quantify densification mechanisms, (iii) examine the influence of metasedimentary gneisses on the composition, density, and seismic velocity structure of intraplated lower continental crust, and (iv) use the field-based observations to develop more robust geophysical models of underplated lower continental crust. The research will provide critical insights into the processes that lead to the formation of magmas, the mechanisms that weaken or strengthen the deep crust, and the processes that facilitate the formation and stabilization of continental crust.
