Geology of the Big Stone Gap Coal Field of Virginia and Kentucky

Description: From introduction: In presenting this paper the writer has two objects in view. The first is to add to the general knowledge respecting the geology of this central district [Appalachian coal basin]. The groups determined in this region will be carried over the adjoining territory if they can be distinguished and they afford a type-section of the Coal-measures where they are probably best developed. The results are not put forth as final, but as representing the most probable conclusions from th… more

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

Description: 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 anom… more

Preliminary Study of the Uranium Potential of the Dan River Triassic Basin System, North Carolina and Virginia

Description: From summary: A preliminary geologic investigation was conducted to determine the uranium potential of the Triassic strata in the Dan River basin system (Dan River, Danville, and Davie County Triassic basins) of North Carolina and Virginia. The pre-Triassic Inner Piedmont basement rocks adjacent to the basins were investigated as potential sources of uranium. Outcrops of Triassic and basement rocks were examined and measured for surface radioactivity by scintillometer. Representative rock and s… more
