Sand and gravel, salt, sandstone and conglomerate all have production over one million tons. Shale and clay are also quarried. 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.
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 ...
The Cleveland Shale (or Cleveland Member) is a sub-unit of the Ohio Shale Formation. [7] [19] The Chagrin Shale underlies the Cleveland Shale. [20] The Bedford Shale generally overlies the Cleveland Shale, with a sharp distinction between the two. In west-central Ohio, more than 150 feet (46 m) of Bedford Shale may lie above the Cleveland Shale.
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 ...
The Bedford Shale in Ohio has been extensively studied since 1943, [23] and the 1954 study by Pepper, de Witt, and Demarest was still considered the classic study of the formation as late as 1991. [24] The Bedford Shale is present throughout much of Ohio. [25] [26] Outcrops extend along Lake Erie from the Ohio-Pennsylvania border west to Lorain ...
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 ...
Grant Lake Formation: Overlies: Fairview Formation: Location; Region Ohio: Country United States: The Miamitown Formation is a geologic formation in Ohio.
The Chagrin Shale is found in north-central and northeastern Ohio, and in northwestern Pennsylvania. [7] The Chagrin Shale reaches a maximum thickness of 1,200 feet (370 m) in eastern Ohio. [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]
