Wilmarth, M.G., 1925, [Selected Geologic Names Committee remarks (ca. 1925) on Carboniferous and Permian rocks of the Midcontinent], IN Wilmarth, M.G., 1938, Lexicon of geologic names of the United States (including Alaska): U.S. Geological Survey Bulletin, 896, pts. 1-2, 2396 p.


Summary:

According to H. Hinds and F.C. Greene, 1915 (Missouri Bur. Geol. and Mines, v. 13), this is same as Lane shale, but according to N.D. Newell, 1935 (Kansas Geol. Survey Bull., no. 21, p. 56), and R.C. Moore, 1936 (Kansas Geol. Survey Bull., no. 22), it includes true Lane shale and 2 overlying formations (Wyandotte limestone and Bonner Springs shale of present [ca. 1938] Kansas Geol. Survey) up to base of Plattsburg limestone. (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.) Newell says (p. 56 cited above): Concreto may properly be used for beds between top of Iola limestone and base of Plattsburg limestone; but it seems preferable to indicate the combined Lane and Bonner Springs shale by hyphenated term "Lane-Bonner Springs shale", where intervening Wyandotte limestone disappears, thus avoiding using a geographic name that gives no indication of its stratigraphic relation to correlative units, and the introduction of a different name where separating limestones thin out.
[The use of a hyphen between undifferentiated formations is not considered proper notation (CSN, 1933).]
