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 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 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 .
Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g., kaolin, Al 2 Si 2 O 5 4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite. [1]
The New Albany Shale is an organic-rich geologic formation of Devonian and Mississippian age in the Illinois Basin of the United States. It is a major source of hydrocarbons. It is a major source of hydrocarbons.
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.
The Acadian orogeny is a long-lasting mountain building event which began in the Middle Devonian, reaching a climax in the Late Devonian. [1] It was active for approximately 50 million years, beginning roughly around 375 million years ago (Ma), with deformational, plutonic, and metamorphic events extending into the early Mississippian.

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]
