This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $429,298 to George Mason University to conduct collaborative research on the integrated late Devonian Earth evolution. The research aims to understand the timing, causes, and consequences of Devonian mass extinctions, and how they can be identified in rocks across North America, Bolivia, and Western Australia. Specifically, the project will: 1) develop an integrated geologic framework linking late Devonian mass extinctions to epeiric black shale successions using biostratigraphy, geochronology, and geochemistry; 2) refine the Macrostrat database to estimate global carbon burial, CO2 drawdown, and O2 buildup; and 3) generate a new uranium and carbon isotope record through late Devonian carbonates in Western Australia to quantify ocean anoxia and carbon burial. The award supports two early-career faculty, expands field geology opportunities for high school students, and involves numerous undergraduate, graduate, and postdoctoral researchers. The research results will be disseminated to both technical and non-technical audiences in English and Spanish. No sub-awards are planned under this grant.
