and 55; Schieber, 2003a). Other types of black shales in the Chattanooga Shale Fm. are pyritized, black shales, while another type possesses either a monopoly or just a scattering of phosphatic nodules (Fig. 2). A fourth type is bioturbated (Fig. 2), which is a black shale containing seemingly, fossilized structures of burrows created bystorm sedimentation. In one of the type sections of the Chattanooga Shale, a deep dark anoxic black shale, there are silty mud rocks with cross‐cutting erosional features. The basin may not have been that deep and dark, but rather still subject to some wave action.This publication presents a revision to the extent of the Devonian Shale-Middle and Upper Paleozoic TPS. The most significant modification to the maximum extent of the Devonian Shale-Middle and Upper Paleozoic TPS is to the south and southwest, adding areas in Tennessee, Georgia, Alabama, and Mississippi where Devonian strata, including ...Jan 1, 1983 · 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.

The Bakken shale, which extends from North Dakota and Montana into Canada, was one of the first plays in which advanced drilling techniques were successfully used to recover oil.

The carbonate buildups exposed on Lake Cumberland are similar to those that produced oil from limestones in the Fort Payne Formation, from reservoirs 5 to 40 ft above the top of the Chattanooga Shale in south-central Kentucky (Munn, 1914, p. 26-29; Wilson, 1971).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 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 Chattanooga Shale is part of the black shroud that blanketed most of the North American craton with anoxic black shale during the late Devonian. These shales indicate an episode of anoxia and stagnation of seawater. Why this occurred is not well understood.

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. 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.The Chattanooga Shale is silty, pyritiferous, and, in some places, partly dolomitic. Spores occur sparsely throughout the shale, but are most common in basal beds. The shale is black in southern Kansas, but it grades northward into gray shale. The Chattanooga Shale is separated from underlying rocks by an angular unconformity.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.Chattanooga shale, a major component of the eastern Devonian shales, covers a wide area from lower Kentucky through Tennessee and into northern Alabama. It contains sizable resources of oil and several critically needed metals. Leaching experiments with sulfuric acid have demonstrated that excellent trace metal solubilization can be obtained ...Shale forms from the pressure of layers of sediment compressing bits of silt that settle into the clay on the bottom of bodies of water. The compressed clay and silt become shale over time. Shale is a sedimentary rock.Abstract. The Chattanooga shale and Maury formation, which typically have a combined thickness of about 30 to 35 ft, crop out on the steep slope between the Nashville Basin and the surrounding Highland Rim; outside the Basin they are present in several river valleys and in folded areas, Throughout most of the area studied these rocks are nearly flat lying, but in the southeastern part they ...
