Crustal Structure & Geophysics
Atomic to tectonic scale examination of crustal geometry, deformation, and evolution using seismic studies, field mapping, fracture analysis, petrography, and geochemical analysis. Some examples of current research by our faculty in Crustal Structure and Geophysics are shown below.

Dr. Hatcher has been working to understand the mechanisms of emplacement of large thrust sheets in a high grade metamorphic terrane. Components of this project involve detailed geologic mapping in and southwest of the South Mountains and Brushy Mountains in North Carolina and areas in northwestern South Carolina, developing techniques to measure map-scale strain, and efforts to better understand the mechanical behavior of different components at all scales within ductile fault zones under different P-T conditions. The map left shows structure contours on the Appalachian Precambrian basement surface.
Tectonics, Structural Geology and Metamorphic Petrology
Dr Jessup's research interests in structural geology and tectonics range from mid-crustal flow to active tectonics. A common theme to his research is the spatial and temporal variability of strain partitioning at different scales and levels in the crust. Dr Jessup characterizes the transition from melt-present flow to solid-state fabric development and quantify the kinematic evolution of high strain zones. His research group is interested in granite emplacement mechanisms, timing and duration of melting, and the relationship between melting and rheology of the crust. Through international collaborative research, Dr Jessup's integration of his field-and lab-based specialties with thermochronology, geochronology and isotopic geochemistry test the evolution of orogenic systems.
Dr. Fedo conducts structural and tectonic analysis of Early Archean rocks of southwest Greenland. In addition, he studies Neoproterozoic and Cambrian strata in order to interpret the early tectonic evolution of the Cordilleran Laurentian margin.
