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.
In Western and central New York, the uppermost member is the dark grey to black organic-rich Oatka Creek shale. Unlike the other Devonian shales in this region, the gray shale at the top of the Oatka Creek thickens gradually to the west, as well as the east, [83] where it divides into the Cardiff member lying above the Chittenango member in ...
The Middlesex Formation is a carbon rich black shale geologic formation found in the Appalachian Basin. It represents one of several transgressive events (rising sea levels) during the Late Devonian .
The Geneseo Shale is a dark grey to black shale that overlies the Tully Limestone; it includes the Filmore beds. [13] The Tully Limestone is a shallow-water carbonaceous unit. The Moscow Formation (Middle Devonian / Givetian) comprises grey to black shales interbedded with limestones and calcareous mudstones and usually bioturbated. [14]
The upper part of the Cleveland Shale is a black to brownish black [13] silty shale [9] with occasional thin beds of gray shale and siltstone. [5] The upper part is much richer in petroleum [16] and kerogen. [4] [d] When broken open, fresh samples smell like crude oil. [4]
The Blocher consists of brownish-black to grayish-black, slightly calcareous pyritic shale. The Selmier is a greenish-gray to olive-gray shale. The Morgan Trail is a brownish-black to olive-black fissile siliceous pyritic shale. The Camp Run is a greenish-gray to olive-gray shale interbedded with brownish-black shale. The Clegg Creek is a ...
The Rhinestreet Shale is a geologic formation in the Appalachian Basin. It dates back to the Devonian period. The Rhinestreet is an organic or Black Shale found on from the approximately the middle of the Appalachian Basin. [1] Near the Middle of Ohio and Kentucky it reaches the surface on the flank of Cincinnati and Findlay Arches. [2]
