The Rhinestreet is an organic or Black Shale found on from the approximately the middle of the Appalachian Basin.

[1] Near the Middle of Ohio and Kentucky it reaches the surface on the flank of Cincinnati and Findlay Arches.

There are thin beds of non-organic gray shale as well as limestone concretions interbedded throughout the formation.

Duning the Alleghanian orogeny regional uplifting caused the first set of fracturing.

Later during rapid burial from sedimentation the next set of fractures were caused by natural hydraulic-fracturing.
