The Burket Shale or Geneseo Shale is the lowest member of the Harrell Shale/Genessee Group. The Burket is an organic-rich black shale that rests just above the Tully Limestone member of the Mahantango Formation. The geographical extent of the formation includes southern New York, Pennsylvania, eastern Ohio, and West Virginia. The Burket is also ...
The Marcellus Formation or the Marcellus Shale is a Middle Devonian age unit of sedimentary rock found in eastern North America.Named for a distinctive outcrop near the village of Marcellus, New York, in the United States, [3] it extends throughout much of the Appalachian Basin.
The Cleveland Shale (or Cleveland Member) is a sub-unit of the Ohio Shale Formation. [7] [19] The Chagrin Shale underlies the Cleveland Shale. [20] The Bedford Shale generally overlies the Cleveland Shale, with a sharp distinction between the two. In west-central Ohio, more than 150 feet (46 m) of Bedford Shale may lie above the Cleveland Shale.
The New Albany formation consists of brown, black, and green shale with minor beds of dolomite and sandstone. It was deposited under anoxic marine conditions. Pyrite is a common accessory mineral, and parts of the shale have greater than 4% by weight
The Kettle Point Formation, also known as the Kettle Point (black) Shale, is a geologic formation that consists of thinly laminated, siliciclastic, organic-rich black shale with thin to thick interbeds of organic-poor mudstone. It is largely restricted to the subsurface of southwestern Ontario.
After the Burgess Shale site was registered as a World Heritage Site in 1980, it was included in the Canadian Rocky Mountain Parks WHS designation in 1984. In 2012, the discovery was announced of another Burgess Shale outcrop in Kootenay National Park to the south. In just 15 days of field collecting in 2013, 50 animal species were unearthed at ...
Low permeability shale yielded a poorly drained landscape, cut streams and rivers, which brought in large amounts of sediment—clay, silt and sand up to 500 feet thick—which deposited as the Hell Creek Formation. The formation contains thin lignite beds, along with dinosaur bones, most notably those of Triceratops and Tyrannosaurus.
The Chattanooga Shale is a member of the Devonian Shale-Middle and Upper Paleozoic Total Petroleum System (TPS) stretching from New York to Tennessee that comprises six large petroleum systems. Such systems span Cambrian to Pennsylvanian intervals, and the Chattanooga Shale feeds much of the Appalachian Basin's oil and gas.
