Summary

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

Hints of bluish iridescence are due to the presence of thin films of turgite (2Fe2O3·H2O, hydrous iron oxide), formed by the oxidation of disseminated pyrite in the coal, in the presence of water.

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
