Organic geochemistry and petrology of Devonian shale in eastern Ohio: Implications for petroleum systems assessment
ON COVER – Roadcut of the Devonian Berea Sandstone capped by the Sunbury Shale along Kentucky Highway 10 near Garrison, Kentucky. The lower part of the outcrop consists of interbedded sandstone, siltstone, and shale, with abundant soft-sediment deformation. Bedded shales decrease upward into siltstone and sandstone, which contain storm bedding and soft-sediment deformation (partly hidden on upper bench). The lower interbedded interval is 15–20 ft (4–6 m) thick. Photo courtesy of Cortland Eble.
