Dr. Dustin Sweet

Associate Professor, Sedimentology & Stratigraphy

Ph.D. University of Oklahoma, 2009



My passion involves deciphering tectonic and climatic conditions from the sedimentary rock record. To meet that goal, I undertake a broad spectrum of sedimentary geology research, predominantly field-based supplemented with laboratory data such as grain size spectrums, geochemistry and scanning electron microscopy. Recent projects I have been associated with have focused on the Late Paleozoic ancestral Rocky Mountains, specifically the formation and configuration of the uplifts, the demise of the mountains and curious preservation of ancient landforms, and the climate state during their formation.

Prior to joining the Department, I worked as an exploration geologist at Chevron Energy Technology Company. Specifically, I worked in Lower Congo and Kwanza Basins in west Africa, Baffin Bay in west Greenland, and the northern Colombia margin typically doing play development or regional framework.
