The key objectives of this 4-year project are to: (1) measure the contribution of mineral strength into rock strength, (2) correlate mineral orientations with rock mechanical properties, and (3) analyze the evolution of mineral...
- The University of Maine was awarded a $390,481 Project Grant from the National Science Foundation to support research related to dynamic fragmentation and earthquake energy partitioning. The grant was awarded on March 1, 2022 under the Geosciences program (CFDA #47.050) and will support research activities through February 28, 2025 at the University's facilities in Orono, Maine. The Geosciences program aims to strengthen understanding of Earth's integrated systems through basic research in...
- This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $206,119 to Iowa State University of Science and Technology to conduct collaborative research on characterizing borehole breakouts in anisotropic materials. The project uses two research methods - physical experiments and analysis of well log data - to study how rock layering and anisotropy impact the inference of stress directions from borehole breakouts. The research aims to improve the...
- This two-year Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) provides $174,000 to fund research examining the interplay between fault material strength, roughness and friction at various scales. The award will support work conducted between June 2021 through May 2023 in Santa Cruz, California. As part of its mission to strengthen the national scientific enterprise's understanding of the integrated Earth system, the Geosciences program aims to expand...
- 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...
- This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a collaborative research project to characterize borehole breakouts in anisotropic materials, both in the laboratory and in natural settings. The $180,350 award to Carleton College will involve two primary research methods: 1) physical experiments using analog materials like sand, gelatin, and wax to investigate how rock layering and anisotropy impact breakout formation, and 2) analysis...
This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $365,580 to the University of Maine System to develop a novel method for quantifying stress and strain rate in deformed rocks. The researchers will use laboratory experiments to analyze the roughness of mineral grain boundaries, which directly records stress and flow rate information. The project supports a postdoctoral associate and graduate student training, and the developed analytical protocols will be made publicly available. The outcomes can be applied beyond Earth sciences to engineer the strength of advanced materials like metals, ceramics, and composites. The funding will enable the team to collect high-resolution electron backscatter diffraction (EBSD) data on rock samples deformed under different conditions, allowing them to deliver robust calibrations and evaluate the effects of variables like water content and deformation geometry on stress and flow rate determinations.
