- 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 two-year Project Grant from the National Science Foundation's Division of Earth Sciences, under the Geosciences program (CFDA 47.050), provides $167,774 to the University of Houston to investigate mantle dynamics in the Pacific Northwest through 3D anisotropic seismic velocity modeling. The University will use surface wave tomography to construct a high-resolution model of seismic anisotropy in the region, revealing detailed mantle processes and testing mechanisms for geophysical...
- The National Science Foundation awarded Washington State University a $173,436 project grant under the Geosciences program (CFDA 47.050) to conduct collaborative research quantifying the role of simultaneous large low shear velocity provinces and continents on Earth's cooling history. Over a three-year period from July 2023 to June 2026, the university will use numerical simulations of mantle convection to study how Earth's thermal evolution and internal mantle dynamics are jointly altered by...
- This National Science Foundation (NSF) Division of Earth Sciences Project Grant awarded to the Planetary Science Institute will conduct collaborative research to study the deformation behavior and rheology of subduction zone rocks. The $169,023 award, made under NSF's Geosciences (CFDA 47.050) program, will address two key questions: 1) how the heterogeneous rheology along subduction megathrusts affects fault slip behavior, and 2) how inelastic deformation on- and off-fault impacts strain energy...
- Brown University received a $335,370 Project Grant award from the National Science Foundation Division of Earth Sciences under the Geosciences federal grant program (CFDA 47.050). The award will fund research from July 1, 2023 through June 30, 2026 to evaluate the processes that create, modify and destroy continental crust through studying the transition from normal subduction to slab window formation in southern Patagonia. Specifically, the university will collect new geochemical and...
The National Science Foundation Division of Earth Sciences awarded the University of Washington $334,964 on September 1, 2026, under the Geosciences program to investigate deformation of Earth's rigid outer shell as it sinks into the mantle beneath the northern Andes using naturally deformed xenolith rocks. The project will determine the rheological properties of a lithospheric section below the North Andean Arc in southern Colombia by analyzing xenoliths brought to the surface by volcanic eruptions, examining how crustal material loses density and sinks via gravitational instabilities. Researchers will develop stress profiles and models showing how rheological parameters influence lower-crustal loss at subduction plate boundaries, using experimentally derived flow laws and petrochronology to quantify the strength of density-unstable crust and the deforming mantle beneath. The work addresses how the lower lithosphere deforms in continental subduction systems, with applications to understanding continental bulk composition, high topography formation, volatile recycling into the deep Earth, and magmatism triggering. The University of Washington, Office of Sponsored Programs, serves as the recipient and will deliver the research and STEM workforce education component through student involvement at multiple levels. Performance occurs in Seattle, Washington. The award funds work through August 31, 2029. The assistance type is a Project Grant under CFDA 47.050 (Geosciences), supporting basic research in Earth sciences.
