Geologic studies produced a regional stratigraphic network that correlates the 15-foot sequence in Tennessee with 3,000 feet of interbedded black and gray shales in central New York. The classic Devonian black-shale sequence in New York has been correlated with the Ohio Shale of Ohio and Kentucky and the Chattanooga Shale of Tennessee and ...

The Chattanooga Shale is separated from underlying rocks by an angular unconformity. From north to south, the Chattanooga overlaps rocks ranging in age from Middle Ordovician to Devonian (Lee, 1940). It is present in most of eastern and central Kansas, but it is absent at the northern end of the Nemaha anticline.

The Chattanooga Shale represents the southern extent of a huge delta system that has its remnants today in the coarse red sandstones and shales of the Catskill Mountains that spread southwestward into a basin that became starved for oxygen. [en] Chattanooga shale samples from DeKalb County, Tennessee, were studied with an electron microprobe. Preliminary results show that uranium in concentrations up to 130 ppM is not dispersed uniformly within the kerogen or inorganic matrix. Distinct uranium minerals, such as uraninite, apatite, and titanium bearing oxides, ranging in size from 3 to 180 μm, are evident on shale surface exposed ...This shale, called the Chattanooga Shale, contains uranium and has been dated at 350 million years old. The presence of pyrite and organic matter and an almost complete lack of fossils suggest that the Chattanooga Shale was deposited in stagnant, oxygen-deficient seawater. Mississippian PeriodThe Chattanooga Shale of the Newman Ridge syncline lies stratigraphically above the Silurian Hancock Dolomite and below the siltstone and shale of the Mississippian Grainger Formation. Core examination indicates that the Chattanooga is predominately a black shale composed of clay, finely divided carbonaceous material, and quartz. Chattanooga Shale. Farther west, black shales were deposited in a thin unit (less than about 10-20 m thick) over a wide area (Chattanooga Shale) during Late Devonian and Early Mississippian. Offshore equivalent of the 3000 m thick Catskill clastic wedge. An important marker bed for regional correlation.

Calculated shale reserves in Gassaway plus Maury formations in DeKalb County, Tennessee are 595 million short tons of 55 ppm U and inferred reserves are more than 8,000 million tons.
The second field trip stop is up the southeast flank of the anticline along Tennessee SR-111 east of Dunlap to review the nearly continuous exposure of the Paleozoic section from the Devonian-Mississippian Chattanooga Shale to the top of the Mississippian.In this area, the Silurian Rockwood Formation may be observed as gently dipping beds below remnants of the Devonian Chattanooga Shale, as well as higher-angle beds which have been thrust above that layer (See Figure 4 in Wilson, 1986). The overlook also provides a view of the western portion of the Valley and Ridge province and Waldens Ridge ...The shale members of the Chattanooga (Woodford) Shale represent a third-order depositional sequence that is bounded below and above by unconformities.

This environment creates an organic-rich shale that is an important source of hydrocarbons throughout the Midcontinent. Geochemical analysis of the Chattanooga shale using various techniques will provide additional information on oil-source rock correlations. This will provide insight on the potential ofIs the Chattanooga Shale really an ore? Though there are several others, the last erroneous statement of Mr. Froede I will address is the following: Levels of uranium found within the shale are sufficiently high to qualify the shale as a uranium ore (Upham, 1992, p. 47).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.
