Maps showing coal resources of the Honaker Quadrangle, Russell, Tazewell, and Buchanan counties, Virginia

The Honaker quadrangle lies in two physiographic provinces.  The northern half of the quadrangle is part of the Appalachian Plateaus province, where the coal-bearing formations of Pennsylvanian age are nearly flat lying or very gently dipping.  Diagonally extending east-northeastward across the middle of the quadrangle are several belts of faulted, overturned, and steeply dipping rocks of Mississi

This report is part of a study to describe the hydrologic framework needed to evaluate the water resources of the Paleozoic age aquifers in the Northern Great Plains coal region (fig 1). Preliminary studies by the U.S. Geological Survey and State agencies in Wyoming, Montana, and South Dakota have indicated that these aquifers might provide significant percentage of the water requirements for coal
