Bartley has worked on varied problems in field-based structural geology and regional tectonics. Recent field research has particularly focused on processes during the growth of igneous intrusions and involves field studies in the Sierra Nevada and the Wasatch Mountains. Other research has concerned the Cordilleran orogen of the western U.S., including (1) the origins of low-angle normal faults and of the metamorphic core complexes thus generated, (2) time-space patterns of magmatism and tectonism, and implications for models for continental extension, (3) Mesozoic contractional systems and their relations to subsequent extensional tectonics, and (4) Cretaceous to Recent, dextral transpressional tectonics in the southwestern United States
