Udden, J.A., Baker, C.L., and Bose, Emil, 1916, Review of the geology of Texas: University of Texas Bulletin, no. 44, 164 p., (incl. geologic map of Texas, 1916, scale 1:1,500,000), Revised 1919


Summary:

Pg. 45. Rough Creek shale member of Tesnus formation. Hard, compact, and brittle dark-green, occasionally black shale, 865 feet thick. Basal member of Tesnus formation. Probably disappears in eastern part of Marathon region. Age is Pennsylvanian.
[Type locality not stated. Named from exposures on Rough Creek, Dove Mountain quadrangle, Marathon region, Brewster Co., western TX.]
[GNC remark (ca. 1936, US geologic names lexicon, USGS Bull. 896, p. 1848): Because of prior use of Rough Creek for a Pennsylvanian deposit in central Texas [Rough Creek Bed of Drake, 1893], the USGS has discarded this name and calls the bed lower shale member of Tesnus formation.]
