The Devonian Chattanooga Shale contains an uppermost black shale interval with dispersed phosphate nodules. This interval extends from Tennessee to correlative strata in Kentucky, Indiana, and Ohio and represents a significant period of marine phosphate fixation during the Late Devonian of North America.Foundation Engineering. Pyrite oxidation and expansion in the New Albany black shale have caused serious foundation problems in numerous buildings and structures constructed in the black shale soil horizons in various parts of Kentucky. Pyrite oxidizes, causing various secondary sulfates to form when excavated shale or shale fill is exposed to ...Chattanooga Shale, Mississippi Valley-Type, Ores, Pb Isotopes, Shales. Abstract.

Chattanooga shale General relations The Chattanooga shale is a black organic pyritiferous marine shale that is generally, very fine grained and sparsely fossiliferous. It is part of a persistent terrane of black shale deposited over much of the interior of North America during Middle Devonian, Late Devonian, and early Mississippian time.Abstract. In 1953 the Chattanooga shale in the Sequatchie anticline was tested for its uranium content by seven diamond drill cores. Concurrent with the drilling, geologic field …Chattanooga Shale.

Distribution of Upper Devonian-Lower Mississippian Misener Sandstone, superimposed on sub-Chattanooga subcrop map, Salina basin by K.D. Newell. KGS Open File Report 89-18. Discussion. The Misener sandstone is a basal transgressive sandstone developed at the base of the Upper Devonian-Lower Mississippian Chattanooga Shale.Anisotropy, at elevated pressures caused mainly by preferred orientation of clays (illite) parallel to bedding, ranges from 20% (V p) and 19% (V s) for a sample of New Albany Shale to 30% (V p) and 35% (V s) for a sample of Chattanooga Shale. The degree of clay mineral alignment in the shales is constrained by "orientation indices" produced ...Fort Payne Formation - Bedded chert; calcareous and dolomitic silicastone; minor limestone and shale; scattered lenses of crinoidal limestone. Thin green shale (Maury) at base. Average thickness about 250 feet (475 in Wells Creek area); and Chattanooga Shale - Black carbonaceous shale, fissile. Thickness 0 to 70 feet; average about 20 feet.

Between the Chattanooga shale and the underlying limestone in parts of Tennessee and Kentucky is a clayey gray to brown zone as much as several feet thick. This represents an interval of limestone that has been leached by sulfuric acid formed by oxidation of the abundant pyrite in the black shale. Alteration of the limestone decreases with distance from the base of the black shale; several stagesThe Chattanooga Shale is equivalent to the Ohio Shale, the Antrim Shale, and the New Albany Shale in surrounding states.

This section is capped by the Chattanooga Shale formation, which misled designers about the extent of solutioning. They mistakenly concluded the Chattanooga Shale had served as an impervious cap or roof that protected the underlying limestone.
