Summary:
Pipe Creek black shale underlies Hanover shale and overlies Portage (Nunda) sandstone. Traceable from Lake Erie to Genesee River. Only 2 feet thick on Walnut Creek, but thickens eastward. [See entry under Silver Creek shale.]

Summary:
In outcrop in western NY, the Java consists of a basal black shale, the Pipe Creek Shale Member, and an overlying gray shale and mudrock with scattered beds of black shale and siltstone, and abundant limestone nodules, the Hanover Shale Member. The Pipe Creek thins to the east and feathers out in northern Stuben Co. The Hanover, however, thickens to the east and grades laterally into the Wiscoy Sandstone Member. The Pipe Creek rarely exceeds 25 ft in thickness, but makes up much of the radioactive black shale in the Java. In the subsurface, it extends south from western NY about 450 mi to Scott Co., VA. It thins to a featheredge in OH, KY, and TN. The Hanover is recognizable in the subsurface southward from western NY to eastern KY and adjacent southwestern VA and northeastern TN. Where the Pipe Creek pinches out, the Hanover cannot be separated from the Angola Shale Member of the West Falls Formation. The two grade westward into the upper part of the Olentangy Shale in central OH, and in central TN, the combined shales are equivalent to the upper unit of the Dowelltown Member of the Chattanooga Shale.
