Ettensohn, F.R., Rice, C.L., Dever, G.R., Jr., and Chesnut, D.R., 1984, Slade and Paragon Formations; new stratigraphic nomenclature for Mississippian rocks along the Cumberland Escarpment in Kentucky, IN Contributions to stratigraphy: U.S. Geological Survey Bulletin, 1605-B, p. B1-B37.


Summary:

The Holly Fork Member of the Slade Formation, used informally by Ettensohn (1977) and here named, consists of dolostone and calcilutite. It was previously included in units here excluded from the Cumberland Escarpment area of east-central and northeastern KY. Unconformably overlies the Armstrong Hill Member and unconformably underlies the Tygarts Creek Member of the Slade. Thickness ranges from 0 to 5 m. Age is Late Mississippian.
