Abstract

An erosional unconformity separates rocks of Pennsylvanian age from underlying rocks of Mississippian age in a part of the Cumberland Plateau in northern Tennessee and southeastern Kentucky. This erosion surface controlled deposition of the overlapping Pennsylvanian sediments and accounts for the discontinuous nature of the sedimentary units. Presumably overlap advanced from the S. and E. In this area, structural disturbance is at a minimum except for broad uplift and warping. Minor slumping was observed near the base of the Pennsylvanian.
