Summary:
Duskin Creek formation of Lee group. [Duskin formation used on p. 30, 39, 63, and in headings on p. 68, 170, 179; Duskin Creek formation used in heading on p. 53, where occurs first description.] Top formation of Lee group in Southern Tennessee coal field. Its top member is a heavy, thick-bedded, very hard, yellowish sandstone, of which 75 feet remains uneroded. Underlying part of formation consists of about 150 feet of shale with a few thin-bedded, shaly, impure sandstones. The shale is usually of dark-blue or gray color and contains several coal beds. In some places the shale is iron-stained and weathers into long, thin slivers. The formation varies in thickness from 0 to 125 feet. It rests on Rockcastle sandstone. [Age is Early Pennsylvanian (early Pottsville).]
Well exposed on Duskin Creek, a tributary of Piney Creek, which flows by Spring City, Rhea Co., southeastern TN.

Summary:
Pg. 4-5. Duskin Creek formation was used for beds presumably overlying Rockcastle, and including Dorton shale (new) of this report. Type section of Duskin Creek, which is along this tributary of Piney River, however, consists of beds of Vandever formation that actually underlie the Rockcastle. This error is believed to have been due to failure to identify the Rockcastle because of its local shaly character. For this reason, the name Duskin Creek is no longer used.
[Abandoned. See Rockcastle.]
