Description: Shales in the Devonian of Kentucky, USA. This weathered black shale outcrop is part of the New Albany Shale of Kentucky and Indiana. The unit consists of dark-colored, chippy-weathering, 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.
