Paleotopographic-structural Controls on Thickness and Composition of Pittsburgh Coal in Southwestern Pennsylvania.
Abstracts With Programs Geol Soc America 1971 Oct; 3(7):1 pages
Data on roof-rock type, coalbed thickness, and the sulfur and ash content of the upper and the lower part of the main seam of Pittsburgh coal were obtained from about 550 cores taken in a 120- square-mile area that is now an underground mine in eastern Green County, Pennsylvania. The area of the study is in a northeast-trending zone on the east side of the Appalachian plateau where amplitudes of folds change abruptly from 300 to 600 feet. To the northeast, in and near this zone, the Upper Freeport and the Lower Kittanning coalbeds also show evidence of paleotopographic-structural control.
