Summary:
Henley Bed forms base of Borden Formation, below the turbidites of the Farmers Member, at Morehead, KY. Composed of gray shale, the Henley represents a time of increased oxygenation of the seafloor relative to the anoxic conditions associated with the deposition of the underlying Sunbury Shale. Thickness of the Henley Bed varies from a maximum of 90 ft at the northeast end of the outcrop belt to a minimum of 10 ft in the Morehead area. The Henley represents hemipelagic sedimentation prior to the active progradation of the Borden delta. Age is Early Mississippian. The Kinderhookian/ Osagean boundary occurs within the Henley. Equivalent to the uppermost part of the Price Formation of WV.
