Explanation of the regional tectonic map of the southwestern coal field of Virginia
The result of this study is a single tectonic map of the southwestern coal field of Virginia, which lies within the southern portion of the Cumberland Plateau. The tectonic map was produced by compiling previously identified and plotted major structural geologic features situated in southwestern Virginia and adjacent portions of Kentucky and West Virginia. Remote sensing imagery and published geologic reports were also utilized in the generation of this tectonic map. Except for the Cumberland overthrust block and its related thrust faults, the major faults within the southwestern Virginia coal field are high-angle normal and right-lateral strike-slip faults showing apparent displacements ranging from a few tens of feet (few tens of meters) to several miles (several kilometers). Folds within the coal field are broad, gentle flexures which include anticlines, synclines and a monocline with amplitudes measured in tens of feet to hundreds of feet (tens of meters to hundreds of meters). Brief descriptions of the general geometry and structural characteristics of the tectonic features are included for use with the regional map as an aid in conducting detailed geologic and environmental investigations. Evidence of structural faulting associated with the Gladeville anticline ( Indian Creek'' lineament) is also presented. 41 refs., 5 figs.
