Summary
[edit]DescriptionMiddle Mercer Coal under Lower Mercer Limestone (Middle Pennsylvanian; Frazeysburg Pit, Muskingum County, Ohio, USA) (41378290895).jpg |
Limestone over coal over shale in the Pennsylvanian of Ohio, USA. The Bowerston Shale Company was founded in the fall of 1929 by Samuel D. Milliken. They have brick manufacturing plants in Bowerston, Ohio and Hanover, Ohio. The Hanover plant makes bricks using rocks derived from two quarries that I know of - the Hanover Pit and the Frazeysburg Pit. I have visited the latter, with kind permission of the Bowerston company. The Frazeysburg Pit targets shales in the Pottsville Group. The shales are excavated and left in piles in the quarry to weather. Limestones and sandstones are excluded from the shale piles. Shale material is eventually trucked to the Hanover Plant, where it is processed into bricks. Seen here is an outcrop in the new/southern quarry of the Frazeyburg Pit in northwestern Muskingum County, Ohio. The ledge at the top of the photo is composed of fossiliferous limestones. This is the Lower Mercer Limestone, a Middle Pennsylvanian-aged, laterally persistent, marine limestone unit in the Pottsville Group. It is richly fossiliferous, principally dominated by brachiopods and crinoid stems. The dark-colored horizon (mostly in the shadows), below the limestone, is the Middle Mercer Coal. In eastern Ohio, it ranges in composition from bituminous coal to cannel coal.
