Ohio's State Invertebrate Fossil, is a trilobite found in the formation. The Southern Hemisphere where Ohio was located at the end of the Ordovician experienced a widespread glaciation, around 438 million years ago. Sea level dropped due to the glaciation, accompanied by a subsidence of the land.
shale: Location; Region: Ohio: Country: United States: The Ohio Shale is a geologic formation in Ohio. It preserves fossils dating back to the Devonian period. See also.
The largest deposits are found in the remains of large lakes such as the deposits of the Green River Formation of Wyoming and Utah, USA. Large lake oil shale basins are typically found in areas of block faulting or crustal warping due to mountain building. Deposits such as the Green River may be as much as 2,000 feet (610 m) and yield up to 40 ...
Major oil shale deposits are located in the Democratic Republic of Congo (equal to 14.31 billion metric tons of shale oil) and Morocco (12.3 billion metric tons or 8.16 billion metric tons of shale oil). Deposits in Congo are not properly explored yet. [7] In Morocco, oil shale deposits have been identified at ten localities with the largest ...

Utica Shale drilling and production began in Ohio in 2011. Ohio as of 2013 is becoming a major natural gas and oil producer from the Utica Shale in the eastern part of the state. [10] Map of Ohio Utica Shale drilling permits and activity by date. [11] [12] In 2011 drilling and permits for drilling in the Utica Shale in Ohio reached record highs ...
The Shakopee was deposited in a peritidal setting and is divided by an unconformity. The unconformity left river valleys that were filled with siliciclastic material that was covered by marine deposits. Facies-defining cycles are divided into grainy carbonate, muddy carbonate, sandstone, shale, and Stromatolitic–Algal mat Boundstones. [17]
