Ohio produces three billion dollars worth of natural gas and $844 million of oil annually. Coal deposits were first recognized in the 1740s by early settlers and were mapped as early as 1752. Decreased demand due to increased natural gas production has reduced coal mining in the 2010s, although one underground mine and three surface mines ...
The Cleveland Shale is a shale geologic formation in Ohio in the United States. The Cleveland Shale underlies much of northeast Ohio in beds of varying thickness. In northeast Ohio, the member does not appear east of the Grand River. [7] Measurements taken in northeast Ohio show the Cleveland Shale to be 7 feet (2.1 m) [7] to 100 feet (30 m ...

[7] In Ohio, the Chagrin Shale is thin in the west, [2] [3] and thickens as it proceeds east. [7] The Chagrin Shale also extends south into West Virginia. [9]
The Cuyahoga Formation is a geologic formation in Ohio. The age of the formation is difficult to determine, because of a lack of diagnostic fossils . Roughly, the formation dates from the Late Kinderhookian (354.8 to 350.8 million years ago) to the Middle Osagean (347.7 to 344.5 million years ago). [ 1 ]
