The U.S. National Science Foundation (NSF) is offering a federal grant opportunity titled "Petrology and Geochemistry," aimed at supporting basic research on the formation and modification of planet Earth through igneous and metamorphic processes. Eligible applicants include non-profit organizations, other federal agencies, federally funded research and development centers, and institutions of higher education, with a focus on proposals that address petrology, high-temperature geochemistry, and the development of analytical tools and models. This program is significant for advancing our understanding of geological processes and enhancing broader impacts in the geosciences, with an estimated total funding of $16 million and approximately 60 awards expected. Proposals are accepted at any time, and interested parties can reach out to NSF grants.gov support at grantsgovsupport@nsf.gov for assistance.
