Full Title: Pennsylvanian Correlations In The Eastern Interior And Appalachian Coal Fields
Author: Harold R. Wanless
From the original introduction: The lithologically complex Pennsylvanian successions in the eastern United States are traced and classified with difficulty, but the great economic value of the coal, clay, shale, and other mineral resources, and the abundant and well-preserved plant and invertebrate fossils contained therein have stimulated detailed studies...This paper presents the results of field studies of Pennsylvanian stratigraphy in Illinois, Indiana, and western Kentucky from the Lonsdale, Cutler, West Franklin, or Madisonville limestone to the base of the Pennsylvanian, and in eastern Kentucky, in Virginia, in southern Ohio, and in southwestern West Virginia, from the Brush Creek limestone, lower Conemaugh, to the base of the Pennsylvanian. This part of the Pennsylvanian is equivalent to the Des Moines and Morrow series of the Western Interior basin. Studies of the younger Pennsylvanian strata of Illinois and Indiana have been carried on principally by J.M. Weller and W.A. Newton, and the sequence for an area in eastern Illinois is described in another publication (Newton and Weller, 1937). A section of younger Pennsylvanian south of the Rough Creek fault in Webster County, western Kentucky, reported by L.C. Glenn (1922, p. 103-121, fig. 31), is about 100 miles from exposures of strata of similar age in Illinois, and the two sections have not yet been satisfactorily matched. Time did not permit the writer to study the upper Conemaugh and Monongahela beds of Ohio, West Virginia, and northeastern Kentucky. Since much of the field work was correlating between various States and districts in the Eastern Interior and Appalachian basins, correlations within each basin are discussed first, and correlations between the two basins are discussed later in the paper. Plates 1 and 2 show graphically correlations in the Eastern Interior basin, and Plates 3 to 8 show correlations in the Appalachian basin. Plate 9 shows the principal members of the Illinois, western Kentucky, Indiana, Ohio, West Virginia, eastern Kentucky, and Virginia sections and is a general key to the other correlation diagrams. The two coal basins and the principal outcrop sections studied by the writer are outlined in Figure 1. The faulted and folded belts associated with variation in Pennsylvanian section are shown in Figure 2.
