Rory McFadden


Assistant Professor in Geology and Environmental Studies

In my research, I use field-based structural geology, petrology, tectonics, and geochronology to investigate the Earth's crust and lithosphere. Mostly, I study intensely deformed, deep crustal rocks to examine the processes and timescales of mountain building and crustal deformation. I am especially interested the rates and processes of deformation in crustal-scale shear zones (e.g. mylonite zones) that help move deep crustal rocks toward the surface of the Earth. I have worked in Idaho, New Hampshire, California, Panama, Australia, and Antarctica.
