Wilmarth, Secretary of Committee on Geologic Names, USGS unpub. corr. chart, Oct. 1936, sheet 1


Summary:

Pg. 47, 53. Rakes Creek shale bed of Tecumseh shale member of Shawnee group. Rakes Creek shale is proposed for upper unit of Tecumseh shale member, i.e., for interval between Ost limestone bed below and Rock Bluff limestone above [lower Deer Creek limestone beds are absent in Nebraska, R.C. Moore]. Thickness 20+/- feet. Age is Pennsylvanian.
Type locality: on Rakes Creek, in NW/4 sec. 5, T. 10 N., R. 14 E., Cass Co., southeastern NE.

Moore, R.C., 1936, Stratigraphic classification of the Pennsylvanian rocks of Kansas: Kansas Geological Survey Bulletin, no. 22, 256 p., See also "Modern classifications of the Pennsylvanian rocks of eastern Kansas and southeastern Nebraska," compiled by M.G. Wilmarth, Secretary of Committee on Geologic Names, USGS unpub. corr. chart, Oct. 1936, sheet 2


Summary:

Pg. 48, 180. Rakes Creek shale member of Tecumseh shale of Shawnee group. Is light-bluish to brownish clayey and sandy shale, and in most places includes a fairly persistent sandstone; is mostly unfossiliferous. Thickness 10+/- feet. Overlies Ost limestone. Recent study by me in Nebraska, western Iowa, and northwestern Missouri, indicates that Rock Bluff limestone, which next overlies Rakes Creek shale is certainly = "middle Deer Creek limestone" in Kansas; but this need not make use of Rakes Creek shale inapplicable in Kansas. Upper boundary of Rakes Creek may be considered as extending to slightly higher stratigraphic plane in north than in south. [Moore's 1936 revised classification for Kansas shows, on p. 48, Rakes Creek shale separated from Rock Bluff limestone by Ozawkie limestone and Oakaloosa shale.] Age is Late Pennsylvanian (Virgil).
