J. Wright Horton, Jr., Ph.D.
Wright is an emeritus Research Geologist in the USGS Florence Bascom Geoscience Center. He has decades of experience in southern and central Appalachian geology, served as co-leader and leader of the USGS Chesapeake Bay Impact Crater Project, is involved in eastern U.S. earthquake studies, and explores terranes and basins beneath the Atlantic Coastal Plain.
Research Interests
Structural geology and tectonics, metamorphic and igneous rocks, impact craters and crater materials, fault zones and fault rocks, Southern and Central Appalachian regional geology and tectonics, pre-Cretaceous terranes and basins beneath the Atlantic Coastal Plain, significance of Mineral, Virginia, earthquake for understanding intraplate earthquakes in eastern North America, geologic mapping, hydrogeology, scientific drilling, geologic interpretation of potential-field geophysics, and multidisciplinary collaborations.
