The Basin Analysis & Helium Thermochronology group at UConn focuses on reconstructing ancient phases of mountain building and erosion to understand how tectonics, erosion, and climate interact to influence Earth’s dynamic mountain belts. Dr. Fosdick and her students draw upon numerous methods in our research, including field mapping and stratigraphy, low-temperature thermochronology, provenance analysis, geochronology, and structural reconstructions.

Ongoing thermochronology and basin analysis projects include work in the Magallanes-Austral Basin in the Patagonian Andes, the Argentine Precordillera and Sierras Pampeanas of the southern Central Andes, the San Andreas Fault System, and the Basin and Range Province.
