The National Science Foundation (NSF) is offering a federal grant opportunity titled "Chemical Evolution of the Solid Earth and Volcanology," aimed at advancing fundamental knowledge about the Earth's origin and evolution, including its core, mantle, and continental crust. The program encourages a diverse range of research activities, including laboratory, field, experimental, theoretical, and computational studies focused on high-temperature geochemical and petrologic processes, volcanology, and natural hazards. With an estimated total program funding of $18 million and approximately 60 awards expected, proposals can be submitted at any time, and interested applicants can reach out to NSF grants.gov support at grantsgovsupport@nsf.gov for assistance.
