Late Mesozoic and Cenozoic Stratigraphic and Structural Framework Near Hopewell, Virginia (open access)

Late Mesozoic and Cenozoic Stratigraphic and Structural Framework Near Hopewell, Virginia

From introduction: This study was undertaken as part of the U.S. Geological Survey's (USGS) Reactor Hazards Reduction Program. One of the goals of this program is to contribute to the growing recognition and cataloging of Cenozoic faults in the Atlantic Coastal Plain. Once the faults are recognized and cataloged, the stress field and resulting tectonic framework that produced these faults can be determined. This study defines the stratigraphic and structural relationships of a tectonically anomalous area in the vicinity of Hopewell, Va.
