Corbin conglomerate lentil of Lee formation. Coarse pink sandstone or conglomerate, 90 feet thick, forming topmost member of Lee formation in Richmond quadrangle. Overlain by Irvine formation (Neocene?). [Age is Pennsylvanian.]
[Named from Corbin, Whitley Co., central KY.]

Corbin conglomerate lentil. Later studies [post-1898] by D. White show that top of Lee formation properly belongs at top of Rockcastle conglomerate member and that Corbin conglomerate lentil and the shales separating the Corbin and Rockcastle properly belong to horizon of Sewell formation and are probably to be correlated with Sharon conglomerate member of Pottsville formation. Age is Pennsylvanian.
Named from Corbin, Whitley Co., central KY.

Corbin raised to formation rank and assigned to Breathitt Group. Lee Formation is "dropped" from usage. As used in this study the Corbin Sandstone consists of a series of local sandstone bodies that interfinger laterally with the Grundy Formation (new). These sandstone bodies are much smaller in extent than the Bee Rock, Sewanee, and Warren Point Sandstones, also assigned here to Breathitt Group. Corbin forms a northeast-southwest-trending belt approximately 40 mi wide and reaches a maximum thickness of 105 m. Most of northwestern edge has been eroded.
[According to the text, the Corbin is restricted to the northern and northwestern part of the study area. On large cross sections, plates 2-6, unit is shown only in KY. On plate 7, a collection of generalized dip and strike sections, Corbin is shown in WV, along the Catlettsburg dip section, as well as in KY. Fig. 11, illustrating the distribution of Corbin, shows unit and laterally equivalent lithologies extending from TN to southern OH and western WV. Fig. 5, a stratigraphic framework, shows Corbin only in northern TN. Until further clarification, GNU records will carry Corbin only in KY and TN.]
