Full Title: Pennsylvanian Geology of a Part of the Southern Appalachian Coal Field
Author: Harold R. Wanless
The Pennsylvanian strata of western Virginia, southeastern Kentucky, Tennessee, and northwestern Georgia consist of shales, sandstones, siltstones, numerous coals, several conglomerates, some thin bands of ironstone, and a few limestones. There is a maximum thickness of nearly 6000 feet near Big Stone Gap, Wise County, Virginia. The strata are of early Pennsylvanian age, equivalent to the Pottsville and the lower part of the Allegheny of Pennsylvania. The region is divided by anticlines, thrust faults and state boundaries into six or more segments where the strata have been differently named and classified. The coals of minable thickness have been named in the many mining districts in the area, and some massive cliff- or bench-forming sandstones or conglomerates, a few thick shales, and some marine limestones have been named; most of the other lithologic units are unnamed. Field studies permitted the correlation of many of the coals and other named beds or formations between separated areas and a general classification of the strata for the area of this report was made, as follows…
