GEOLOGY The main geologic subdivisions of the Ohio Basin are shown dia- Le Conte’s Geologic Map of the Eastern United States! and from State geologic maps. Limestone and shale are the most common bedrocks. The most extensive formations are the Carboniferous, which extends through the eastern and southeastern portion of the basin; the sub-Carboniferous in the central portion, and the Cam- brian and Silurian, which cover large areas of the north-central and southeastern portions of the basin. The northern part of the water- shed, above a line which reaches as far south as Cincinnati, is overlaid with glacial drift, which forms the extraordinarily deep and fertile soil of the prairies in the western part of the basin. In the mountain region of the Appalachians the soil is light and sandy, and in the level areas of the Mississippi plains it is alluvial, consisting of a rich loam mixed with clay. The mineral deposits of greatest economic and industrial importance are coal, iron ores, petroleum, and natural gas. The most extensive coal measures are those comprised. in the Appalachian fields, extending - from western New York southwest to Alabama, and the Restart Tnte- . * Le Conte, Jos., Elements of Geology, Fourth Edition, p.302.
