Summary:
The Tygarts Creek Member of the Slade Formation, here named, consists of light-gray calcarenite with local stringers of dolomite. This unit was formerly called the Reelsville-Beech Creek Limestone by McFarlan and Walker (1956), which is excluded from the Cumberland Escarpment area of east-central and northeastern KY. Occurs throughout the outcrop belt of the Slade Formation. Disconformably overlies or intertongues with the Armstrong Hill or Holly Fork Members of the Slade; conformably underlies the Ramey Creek Member. Thickness varies from 1 to 10 m. Age is Late Mississippian.
