The GeoStructure Group at the University of Arizona is focused on the development of the Earth’s major orogenic belts and related sedimentary basins. Ongoing projects are situated along archetypal examples of collisional, retroarc, and retreating continental margins and their associated fold-thrust and foreland basin systems.
We are also focusing on extensional systems and associated basins in the Himalaya, Tibet, and the North American Cordillera. Methods applied include surface and subsurface mapping; regional structural analysis; U-Pb, Th-Pb, and 40Ar/39Ar geochronology and thermochronology; metamorphic petrology and thermobarometry; detailed and regional sedimentology and conventional provenance analysis; isotopic (Sr, Nd, and U-Pb detrital zircons) provenance analysis; subsidence modeling; traditional and kinematic sequence stratigraphy; and geodynamic modeling. Our efforts are aimed at developing both fundamental understanding and solving regional-scale tectonic problems with large datasets.
