The AU extends south from south-central Kentucky through eastern Tennessee, northwest Georgia, northern Alabama and into eastern Mississippi.Across Tennessee, the Chattanooga Shale consists of the Blocher, Flynn Creek, Dowelltown, and Gassaway members (Schieber and Over, 2005) and at least fourteen depositional sequences that have local to regional development (Schieber, 1998a; Fig. 2) and possible global expression as indicated by correlation to global black shale and extinction ...

Microfossil evidence indicates that the Cowley is a facies of the sequence from the St. Louis Limestone to the Chattanooga Shale (Thompson and Goebel, 1968). The "Cowley facies" is herein adopted for use in Kansas. Silty and siliceous dolomite, limestone, and dolomitic siltstone, and variable amounts of dark, opaque, microfossiliferous chert ...

The Chattanooga shale has three members: the Hardin sand­ stone, the Dowelltown, and the Gassaway (youngest). The Hardin sandstone member grades into the overlying Dowelltown member. It is a local thickening of the basal sandstone bed of the Chattanooga shale, and is restricted to the vicinity of Wayne,

It is a local thickening of the basal sandstone bed of the Chattanooga shale, and is restricted to the vicinity of Wayne,Devonian Black Shales Eastern US Chattanooga, New Albany, Ohio Shales: The Mid-Late Devonian black shales of the Appalachian, Illinois, and Michigan Basins have long been studied to provide clues to past climates, ocean ventilation, mass extinctions, and general earth history.

The Chattanooga Shale is a laterally extensive, easily recognizable black to gray-black shale present in the subsurface throughout most of Kansas (see Goebel, 1968b; Lambert 1992, this volume, for summary of Chattanooga Shale distribution and internal stratigraphy in Kansas). The Chattanooga in Kansas long has been regarded as undifferentiated ...The Chattanooga shale contains insoluble organic matter (kerogen) derived from terrestrial (humic) and from marine (sapropelic) sources. Kerogen from sapropelic sources contains more hydrogen than kerogen from humic sources. Thus the hydrogen content of the sapropelic contribution, and of the kerogen, increases toward that part of a shale most ...

A shallow-water origin for the Chattanooga shale-is-indicated by several circumstances-. Any deep-water hypothesis encounters serious difficulties, and the evidence commonly cited in its support is thought to be inapplicable -.

Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al 2 Si 2 O 5 4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite.
