Florence Bascom Geoscience Center
Home
The Florence Bascom Geoscience Center (FBGC) is at the leading edge of scientific research addressing critical societal issues and providing unbiased data and information to decision makers and the public. Our research center is built around five broad science themes: Paleoclimate & Paleoecology, Landscape Science, Geologic Mapping, Hazards, and Special Geologic Studies.
Story on Mid-Atlantic Stream/Sediment Science
FBGC's ecologist Greg Noe's work is highlighted in this great article discussing legacy erosion and sedimentation in Mid-Atlantic watersheds.

Synthesis of geochronologic research on Late Pliocene to Holocene emergent shorelines in the lower Savannah River area of southeastern Georgia, USA
Emergent late Pliocene and Pleistocene shoreline deposits, morphologically identifiable Pleistocene shoreline units, and seaward-facing scarps characterize the easternmost Atlantic Coastal Plain (ACP) of the United States of America. In some areas of the ACP, these deposits, units, and scarps have been studied in detail. Within these areas,...

River terrace evidence of tectonic processes in the eastern North American plate interior, South Anna River, Virginia
We show that long-recognized seismicity in the central Virginia seismic zone (CVSZ) of the eastern North American (ENAM) intraplate setting arises primarily from tectonic processes predicted by new, fully coupled plate tectonic geodynamic models. The study leverages much new geophysical and geologic data following the 2011 Mineral, VA earthquake...

Karst in the Upper Midwest occurs within a thick sequence of mixed carbonate and siliciclastic Cambrian through Pennsylvanian sedimentary rocks, with a minor occurrence of karst in Proterozoic sandstone. Deposition of the sediments occurred on a marine epeiric ramp that spanned much of the North American continent through most of the...
