Most of the rocks of Cambrian through Devonian ages in eastern Kentucky change from miogeosynclinal in the southeasternmost part to cratonic as they rise northwestward onto the Cincinnati arch. All the systems show thinning and beveling toward the arch, and the Cambro-Ordovician shows additional post-Knox pre-Chazy beveling from south to north, apparently reflecting a different pre-Cincinnati arch paleogeography. Middle and Lower Cambrian rocks have fullest representation of finer clastics and carbonates in the fault-bounded "Rome trough."
Oil and gas, apparently indigenous, have been obtained from rocks of Early and Middle Cambrian ages.
