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 ...
Shale is characterized by its tendency to split into thin layers less than one centimeter in thickness. This property is called fissility. [1] Shale is the most common sedimentary rock. [2] The term shale is sometimes applied more broadly, as essentially a synonym for mudrock, rather than in the narrower sense of clay-rich fissile mudrock. [3]
The new thought is that these ocean currents were slowed by blooms of microscopic marine primary producers, which allowed for the settlement of organic-rich sediments at the seafloor, producing many of the economically productive black shale beds that are present today. To this day it remains an intensely researched subject by scholars and ...
[1] [2] It is correlated with Swedish alum shale being its younger facial eastward continuation, and both being a part of the Baltoscandic Cambrian-Ordovician black shale, together with black shales in the Oslo region in Norway, Bornholm, Denmark, and Poland. [2] [3] Other known occurrences are in North America, [4] the Malay Peninsula, [5] and ...
The greenish rock under the concrete block at top center is the base of the Brainard and is dominantly a sticky green shale with thin beds of purplish gray dolomite. Above the Fort Atkinson is the Brainard Formation. The Brainard is generally a greenish gray to gray dolomitic soft to hard shale. It contains abundant fossils near the base. It ...
Torbanite, also known historically as boghead coal or kerosene shale, is a variety of fine-grained black oil shale. It usually occurs as lenticular masses, often associated with deposits of Permian coals. [1] [2] Torbanite is classified as lacustrine type oil shale. [3]
Organic-rich black shales formed, ultimately producing oil and gas which is now extracted. Black shales hold broadly similar fossil assemblages to Silurian and Ordovician deposits, but have particularly well preserved calcareous stromatoporoid sponge fossils, which are found at the Falls of the Ohio close to Louisville.
