Petrology and Geochemistry (CH)

The Petrology and Geochemistry Program (CH) supports basic research on the composition and structure of Earth materials to explore the nature, origin, and evolution of the earth's crust, mantle, and core. Proposals in this program generally address the petrology and geochemistry of igneous and metamorphic rocks, mineral physics, and volcanology. Topics include major and trace element geochemistry; stable and radiogenic isotope geochemistry and geochronology; experimental mineralogy, geochemistry, and petrology, thermodynamic modeling, chemical aspects of mineral physics; mineralogy and crystallography; ore deposit petrogenesis; physical and chemical volcanology; and analytical method development. Proposals to study extraterrestrial materials will be considered if applicable to understanding Earth formation and evolution.
