The Geodynamics group at the University of Maine applies interdisciplinary research to better understand Earth’s thermal, mechanical and geological evolution. We integrate numerical and analog modeling of dynamic processes with field- and laboratory-based geological studies in regions undergoing active deformation from various parts of the world. We also examine the structure, kinematics and petrology of ancient mountain belts from the perspective gained by our work in active orogens. The information from exposed ancient belts about strain distribution, fabric evolution, metamorphic reaction and melting feeds back into our studies of modern orogens.
