Summary:
The Paragon Formation, here named, is a sequence of shale, dolostone, and limestone which is divided into a lower dark shale member, a clastic member, a limestone member, and an upper shale member. Strata of the Paragon Formation were previously assigned to the Pennington Formation or Newman Limestone, which are here excluded from the Cumberland Escarpment outcrop belt in KY. The Paragon occurs throughout the outcrop belt south of Greenup Co., southward to an arbitrary cutoff against the Pennington at the southern border of KY. Conformably overlies the Poppin Rock Member of the Slade Formation or the Bangor Limestone; disconformably underlies Pennsylvanian units. Thickness varies from 0 to 60 m. Age is Late Mississippian.
