The National Science Foundation awarded a $174,000 Project Grant to researchers at the California Institute of Technology to develop a high-resolution record of mantle-derived rocks. The two-year award, made under the Geosciences program (CFDA 47.050), will support efforts to constrain mantle stirring rates and tectonic regimes through analysis of neodymium and samarium isotope ratios in rocks. The Geosciences program aims to expand fundamental earth science knowledge and understanding of the integrated Earth system through basic research support. Work will be performed in Pasadena, California through August 2023 to construct a detailed isotopic record that can offer new insights into mantle dynamics and historic plate boundary interactions.
