This $518,605 National Science Foundation project grant under the Geosciences program (CFDA 47.050) will fund collaborative research to quantify strain and fluid flow along subduction interfaces. Penn State University will lead efforts to characterize chemical and mechanical processes controlling the healing of subduction zones between large earthquakes. Researchers will study ancient subduction exposures in Japan and Alaska spanning depths of 8-20 km and temperatures of 150-350°C. Electron...
Yale University was awarded a $298,718 Project Grant from the National Science Foundation Division of Earth Sciences under the Geosciences federal grant program (CFDA 47.050). The two-year award beginning June 1, 2023 will support research investigating the loss of volatiles from the early Earth's atmosphere and the resulting redox evolution. Specifically, the university will conduct fluid dynamical simulations modeling Earth's post-impact atmosphere incorporating interior heat and solar...
The National Science Foundation awarded a $135,983 project grant under the Geosciences program (CFDA 47.050) to the University of the Incarnate Word for collaborative research titled "A Geochemical Approach to Quantifying the Magnitude of Strain and Fluid Flow Along the Subduction Interface." The research aims to characterize chemical and mechanical processes controlling the healing of subduction plate interfaces between large earthquakes through observations of ancient subduction...
This National Science Foundation Project Grant award of $139,678 supports research into the influence of fault geometry on shallow frictional sliding in subduction zones under the Geosciences program (CFDA 47.050). The awardee, Planetary Science Institute, will conduct complementary theoretical and numerical analyses to determine how fault zone geometry controls the sliding stability of thrust faults and how shallow slip events nucleate and propagate within a subduction zone fault network over...
This National Science Foundation project grant of $117,832 awarded on July 1, 2022 will support research into the geological processes that have shaped the continental lithosphere beneath New England through time. Funded under the Geosciences program (CFDA 47.050), the investigators from Williams College and research institutions will conduct seismic imaging of the crust and upper mantle using data from deployments of seismometers in New York, Massachusetts, Vermont, New Hampshire and Maine....
This $393,670 National Science Foundation award under the Geosciences program (CFDA 47.050) funds research at the University of California, Davis from March 2022 through February 2025 to test the role of metastable olivine in subduction dynamics and deep earthquakes. The researchers will use state-of-the-art numerical simulations integrating experimental and observational parameters to model various subduction scenarios with and without the presence of metastable olivine. They will compare model...
This National Science Foundation project grant award of $701,062 provides funding from July 1, 2022 through June 30, 2025 to Yale University under the Geosciences program (CFDA 47.050). The award will support research into quantitatively assessing the impact of unequal stresses on geologic processes in subduction zones. Specifically, the grantee will develop theoretical models and apply them to natural samples to evaluate how non-hydrostatic stress affects mineral interface stability, solid solution compositions, and intracrystalline diffusion rates. This has implications for techniques such as diffusion-based timescales and reconstructing deformation, cooling, and exhumation histories. The research involves Ph.D. and undergraduate student participation, as well as public outreach through Yale University's Peabody Museum of Natural History. Fieldwork and laboratory analysis including electron microscopy and microprobe techniques will be performed. The results have the potential to advance understanding of fluid generation in subduction zones and related natural hazards.
