Summary

[edit]
Description
English: The Meigs Creek Coal (a.k.a. Sewickley Coal) is a horizontally bedded bituminous coal horizon in the Upper Pennsylvanian Monongahela Group of eastern Ohio, USA.

Immediately underlying the coal bed is an "underclay", a silty shale that's been subjected to sulfuric acid alteration by the oxidation of pyrite in the coal bed and downward percolation of rainwater and groundwater. The beds above the coal horizon are part of the Benwood Limestone, a succession of interbedded nonmarine, lacustrine limestons and shales (mudshales and mudrocks).

Locality: Narrows Run North outcrop - roadcut on the western side of Rt. 7, just north of Narrows Run (an east-flowing tributary of the Ohio River), northeastern York Township, southeastern Belmont County, Ohio, USA
