Geology and Mineralization
The Chattanooga Shale of Devonian to Mississippian age spreads over an area of some 80,000 km2 from southern Kentucky through central Tennessee into northern Alabama (Fig.I.1). It is a flat-lying, massive, siliceous, pyritic marine black shale, on average about 10 m thick and located at a depth from 30 to 600 m. It unconformably rests upon Leipers Limestone and is overlain by the Maury Formation. The Chattanooga Shale includes three members. At the base and only locally developed is the thin Hardin Sandstone Member. The middle Dowelltown Member, about 5 m thick, has only weak U tenors (av. 23 ppm U).
The Gassaway Member, the upper unit of the Chattanooga Shale,...
