English: Black shales from the Devonian of Indiana, USA. (on display in New Albany, Indiana during the 24-25 September 2004 annual field conference of the Great Lakes Section, Society of Economic Paleontologist and Mineralogists; up-section is to the left; ~0.383 meters of section seen here)

This is a core through part of the New Albany Shale, a Devonian-aged formation in Kentucky, Indiana, Illinois, and eastern Missouri. The unit is dominated by dark-colored marine mudshales of Late Devonian age. These black shales were deposited in a moderately deep, anoxic seafloor environment. This was a widespread lithofacies during the Late Devonian's Global Anoxia Event. The New Albany Shale is equivalent to the Ohio Shale, the Antrim Shale, and the Chattanooga Shale in surrounding states.

The New Albany Shale's member terminology varies from region to region. In southwestern Indiana, where this core was drilled, the New Albany consists of (from the base upward): Blocher Member, Selmier Member, Morgan Trail Member, Camp Run Member, and Clegg Creek Member.

The Blocher Member consists primarily of banded black shale that is variably dolomitic, pyritic, and organic-matter rich.
