Tectonics Thermochronology Sedimentary Basin Analysis
Our research focuses on reconstructing ancient phases of mountain building and erosion to understand how tectonics, surface processes, and climate interact to influence the Earth's dynamic mountain belts. My students and I draw upon numerous methods in our research, including field mapping and stratigraphy, low-temperature thermochronology, provenance analysis, geochronology, and structural reconstructions. Currently, I have ongoing thermochronology and basin analysis projects in the Magallanes (Austral) Basin in the Patagonian Andes, the Argentine Precordillera of the southern Central Andes, and the San Andreas Fault System in California.
The Basin Analysis & Helium Thermochronology Lab houses a SCLM helium gas extraction and measurement system designed for low-temperature (U-Th)/He thermochronology to study thermal and exhumational histories of the Earth's crust and sediments. The lab also hosts a chemistry lab for mineral dissolution, a polarized stereomicroscope, and a petrographic microscope outfitted with a Pelcon automated point counting system.
