Specialties:
The tectonic evolution of continental crust within collisional mountain systems, particularly the Appalachian-Caledonian chain. He maintains active research in the southernmost Appalachians, U.S.A., and in the northernmost Caledonides of artic Norway.



Professor Steltenpohl teaches undergraduate courses in Physical Geology, Structural Geology, Independent Field Mapping and Field Methods. On the advanced level and graduate level he teaches courses in Advanced Structural Analysis, Tectonics, and Geodynamics.  Emphasis is place on field studies, geometric analyses, petrofabrics, phase petrology, and 40Ar-39Ar thermochronology.



Dr. Steltenpohl's primary research interest lie in the tectonic evolution of continental crust within collisional mountain systems, particularly the Appalachian-Caledonian chain. He maintains active research in the southernmost Appalachians, U.S.A., and in the northernmost Caledonides of arctic Norway.

With continued support from the Norwegian petroleum industry (Basin Thermochronology Project - BAT), Dr. Steltenpohl and his students are actively engaged in field and petrologic studies aimed at deducing the extensional history of the north-central Norwegian margin.  Last summer (2000) funding was switched to the "other side" of the Caledonian mountain belt in East Greenland where the oil companies have renewed interest. Work in the Lofoten Islands of Arctic Norway is on slate for the summer of 2001.  Dr. Steltenpohl also has maintained Department of Interior grants (USGS-EDMAP Program) to map bedrock and analyze structures in the Alabama foreland-fold-and-thrust belt (Valley and Ridge Province), Talladega slate belt, and the high-grade Piedmont Province.  This work is in collaboration with the Geological Survey of Alabama (USGS-STATEMAP Project) and is aimed at characterizing small- and large-scale structures in the area to characterize the geological history, delineating possible contamination of ground water, and supplying data to planners coping with rapid urban expansion.



Professional Steltenpohl has cooperative projects that involve workers and facilities at the following institutions: The Alabama Geological Survey; The U.S. Geological Survey; the Norwegian Geological Survey; the Polish Geological Survey; the University of Wroclaw, Poland; the University of Oslo, Norway; the University of Tromso, Norway; the University or North Carolina; University of Florida; Florida State University; and Sandia National Labs, Albuquerque, N.M.
