Geology and Minerals
The Conasauga Shale Field is a Cambrian Period part of the Appalachian thrust and fault region of Alabama, Georgia, and Tennessee, United States. The subterranean formation consists of shales and carbonates over 1,600 - 2,000 feet thick in certain areas. Due to Thrust faulting the overall thickness has been exaggerated in some sources by several thousand feet. Several preliminary drillings found it could be one of the larger reserves of natural gas in U.S. history.
