Chattanooga shale.

The shallow-water theory seems to encounter no such formidable obstacles. We know of no facts that are incompatible with a shallow-water theory; we think that all known facts lend themselves to such an explanation; and we believe that a shallow-water explanation of these black shales is the simpler and sounder of the alternatives.GovInfo | U.S. Government Publishing OfficeThe Chattanooga shale crops out on the steep slope between the Nashville basin and the surrounding Righland Rim, and on many high hills within the basin in Tennessee. Outside the basin the black shale sequence is exposed in several river valleys and around tbe large Lexington Basin of Kentucky, Ohio, and lndiana. The Chattanooga shale in Tennessee, Kentucky, and Alabama is the generally more radioactive part of thin blanket of black shale that once covered large part of eastern and central United States. Correlatives of the Chattanooga, all slightly radioactive, are the New Albany shale of Illinois, Indiana, and Kentucky; the Antrim shale of Michigan ...The branch of geology that deals with the origin and changes of Earth and life through time and space is:

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. The eastern Devonian oil shale resource can yield 400 billion (400 X 10/sup 9/) bbl of synthetic oil, if all surface and near-surface shales were strip or deep mined for above-ground hydroretorting. Experimental work, in equipment capable of processing up to 1 ton/h of shale, has confirmed the technical and economic feasibility of aboveground ...

How did the Chattanooga Shale, a black shale rich in organic matter, form in the Devonian period? This article presents evidence for high-energy events and shallow-water deposition in central Tennessee, USA, based on geochemical, mineralogical and sedimentological analyses. The authors challenge the conventional view of black shale formation and propose a new model of episodic sedimentation in ...

A shale rock sample was scanned by micro-CT technology, tomographic images of the rock sample were obtained, and the three-dimensional structure was reconstructed by Avizo software. ... Sensitivity studies on fracture network variables for modelling carbon dioxide storage and enhanced recovery in the Chattanooga Shale Formation. Int J Oil Gas ...March 7, 1954 View Document 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 work was done to determine the distribution, thickness, and structural setting of the shale.Occasionally the Chattanooga Shale is absent and the entire interval may be Upper Devonian sandstone. These Upper Devonian sandstones are phosphatic, mature quartz arenites referred to the Sylamore Member except where they overlie the Chattanooga Shale. In these cases, the sandstone is recognized as an informal upper member of the Chattanooga.The Chattanooga shale is recognized as a major world uranium province, with estimated reserves of 5,000 t of uranium, but there has been no commercial production. Internationally, uranium has been produced from organic-rich shale, in Sweden and Germany. The Marcellus Shale has not been studied as a potential resource of uranium. In most black shales, such as the Chattanooga Shale and related shales of the eastern interior United States, increased metal and metalloid contents are generally related to increased organic carbon content, decreased sedimentation rate, organic matter type, or position in the basin. In areas where the stratigraphic equivalents of the Chattanooga …

In the central Appalachian Basin, we analyzed the Cleveland Member of the Ohio Shale in the OHLO-2 core from northern Ohio and the KEP-3 core from northern Kentucky (cf. Jaminski, 1997, Jaminski et al., 1998). In the southern Appalachian Basin, we sampled the Chattanooga Shale in the Dupont HGS drillcore from northern Tennessee (cf.Love LG (1965) Micro-organic material with diagenetic pyrite from the Lower Proterozoic Mount Isa Shale and a Carboniferous shale.

The unit name usage by the U.S. Geological Survey (USGS) includes Marcellus Shale and Marcellus Formation.The high Ro values relative to the shallow depth of the Mississippian and the Chattanooga Shale in the Brown well are on the order of Ro values modeled for the same stratigraphic units at present-day greater depths and may reflect uplift of the Ozark dome, located further east, affecting the eastern side of the Cherokee Basin.Based on a concept ...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,the upper Dowelltown Member of the Chattanooga Shale in the southern Appalachian Basin, and the upper Selmier Member of the New Albany Shale in the Illinois Basin. The Huron Member of the Ohio Shale, an organic-rich black shale characterized by large calcareous concretions, sharply overlies the Upper Olentangy Shale in central Ohio. The …Geologic unit mapped in Tennessee: Fort Payne Formation - Bedded chert; calcareous and dolomitic silicastone; minor limestone and shale; scattered lenses of crinoidal limestone.

In the Missouri River valley, thin beds of the shale contain as much as 0.01 percent uranium.The Chattanooga Shale is the distal part of a thick clastic wedge that accumulated during the Late Devonian in the Appalachian Basin and on the adjacent North American craton. Although it has long been assumed that these black shales accumulated beneath the dysaerobic-anaerobic boundary of a deep stratified water column (e.g., Byers 1977 ...Hydraulic fracturing, better known as "fracking," essentially entails drilling into shallow beds of energy-rich shale and injecting a mixture of water, sand and other chemicals to obtain more natural gas at higher and faster rates.However, recent observations and detailed outcrop studies on the Chattanooga Shale of Tennessee and Kentucky have revealed a complex internal stratigraphy which suggest sea-level variations. The lower Bakken of the Williston Basin was deposited during a time span that saw development of many sequences in coeval portions of the Chattanooga Shale ...These studies correlate the classic Devonian black shale sequence in New York with the Ohio Shale of Ohio and Kentucky and the Chattanooga Shale of Tennessee and southwestern Virginia. Biostratigraphic and lithostratigraphic markers in conjunction with gamma-ray logs facilitated long-range correlations within the Appalachian Basin.

Picture shows truncation of black shale packages by erosion surfaces (dashed white lines marked with large white arrows), and illustrates how succeeding black shale packages are draped conformably over these erosion surfaces. Small white arrows point out ...More than 20,000 wells produce gas from Devonian shales in the basin. The wells are commonly 3,000 to 5000 feet deep.

The bitumen of Chattanooga oil shale has been extracted with benzene. The benzene-soluble material was separated into acid, base and neutral fractions with ion exchange chromatography. This separation scheme has been used extensively to separate the organic material in Green River oil shale. The acid fraction was esterified with BF/sub 3//MeOH.
