Chattanooga shale

Abstract. Chattanooga shale, a large and mineral-rich member of the Devonian oil shales of the Eastern United States, is a resource of about 100 billion bbl of oil, 10 million tons of …

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.Mississippian Fayetteville Shale).Metal sources evaluation indicate a mixing model of fluids sourced from high and less radiogenic rocks shown by a broad and linear trend of Pb isotope composition, with the Chattanooga rock and the Jackfork sandstone samples being the most prominent source rocks.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. 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.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.

This study examines the potential hazards to aquatic ecosystems from large-scale exploitation (190,000 Mg/day) of the Chattanooga Shale Formation, an immense reserve of oil shale and uranium in Kentucky, Tennessee, and Alabama. Using existing data on regional ecology, hydrology, mining operations, and raw and spent shale chemistry, we ...At the Harrison Branch section (HBRA) in Blount County, in an exposure near the confluence of Harrison Branch and the Little Tennessee River, this sandstone underlies the Devonian Chattanooga Shale, and it overlies ~43 m of gray limestones and shales that are themselves above the red clastic and minor carbonate rocks of the Bays Formation.Chattanooga Shale and Frog Mountain Sandstone undifferentiated (In areas mapped as Dcfm one or both units may be locally absent) - Chattanooga Shale -- Brownish-black organic shale containing light to dark-gray sandstone and rare limestone interbeds near the base. Frog Mountain Sandstone -- light to dark-gray sandstone with thin dark-gray shale ...The Chattanooga shale was examined and sampled at 7 out­ crop localities in Oklahoma, 10 in Arkansas, and 1 in Missouri, and samples of cores from 2 drill holes in Kansas were also collected. The Late Devonian Chattanooga Shale of Tennessee and Kentucky is in most areas a thin black shale deposit of less than 10 meters thickness. It is a distal equivalent to the almost 3000m thick Catskill sequence, and encompasses most of the Frasnian and Fammenian, approximately 14 million years of earth history. ...Tennessee has no significant proved natural gas reserves and its natural gas production is small. 87,88 Most of the state's natural gas-producing wells are located in northeastern Tennessee on the Cumberland Plateau. 89 Natural gas exploration permits issued in the past decade have focused on exploration in the Chattanooga Shale play, which ...The clay mineralogy of the Chattanooga Shale (illite with no smectite) reflects an erosional origin rather than alteration of volcanic ash. One can only wonder why Mr. Froede claims …

The Fort Payne Formation, or Fort Payne Chert, is a geologic formation found in the southeastern region of the United States. [1] It is a Mississippian Period cherty limestone, that overlies the Chattanooga Shale (or locally the Maury Formation ), and underlies the St. Louis Limestone (lower Tuscumbia Limestone in Alabama).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 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 ...Bonar said Chattanooga shale is too fragile for the high-pressure water fracking treatment, so nitrogen gas replaces some of the water. "Nitrogen is 78 percent of our air, and it's relatively ...The shale most commonly produced is the Chattanooga Shale, also called the Ohio Shale. The US Geological Survey estimated a total resource of 12.2 trillion cubic feet (350 billion cubic metres) of natural gas in Devonian black shales from Kentucky to New York .

Core examination indicates that the Chattanooga is predominately a black shale composed of clay, finely divided carbonaceous material, and quartz. The soluble organic material, bitumen, contained in Chattanooga Shale has been separated from the shale by Soxhlet extraction with benzene. The bitumen has been analyzed for carbon, hydrogen, nitrogen and sulfur (CHNS). The bitumen had a molar hydrogen to carbon ration of 1.6. The bitumen was separated into acid, base and neutral fractions ...Approximately 510 short tons of CO2 were successfully injected into a horizontal production well completed in the Chattanooga Shale formation in Morgan County, Tennessee. After the injection phase ...Experimental investigations on pyrite synthesis indicate that before pyrite can be produced by a reaction involving ferrous iron, the disulphide ion must be formed; in experiments described the ion was obtained by the action of H2S in aqueous solution on elemental sulphur. Conditions under which the experiments were conducted indicate that pyrite will …The larger, connected caves are within the lower part of the Springfield Plateau aquifer (the St. Joe Limestone Member) where it immediately overlies the Ozark confining unit (the Chattanooga Shale). These caves formed at or below the main water table of the aquifer. Small caves are within some sandstone beds of the Ozark aquifer.Mr. Froede has only advanced his argument to the initial level of scientific explanation: the hypothesis. I will restrict my comments to the Chattanooga Shale since I am more familiar with it. While examining Mr. Froede's paper, I tried to keep an eye toward whether there is evidence for his hypothesis in the Chattanooga Shale.
