Black, D.B., and Cuppels, N.P., 1973, Strodes Creek Member (Upper Ordovician); a new map unit in the Lexington Limestone of north-central Kentucky, IN Contributions to stratigraphy: U.S. Geological Survey Bulletin, 1372-C, p. C1-C16.


Summary:

Named as a member of Lexington Limestone. Named for Strodes Creek, Austerlitz quad, Clark Co., north-central KY. Well exposed in many roadcuts along US Hwy 227 and I-64 between type locality and section B of reference section. Consists chiefly of moderately grayish-brown to gray, dense, nonfissile limestone having textural characteristics of mudstone, with minor amounts of gray to reddish-brown, fissile, shaly, argillaceous calcisiltite as partings and in places as beds. Readily recognized by its bouldery aspect attributed to combination of pinch-and-swell bedding, ball-and-pillow structure, and bulbous stromatoporoids. Thickness at type is 7.2 ft. Considered a lens or possibly a tongue within Millersburg Member of Lexington Limestone. Contains bryozoans, pelecypods, gastropods, corals, ostracodes, brachiopods, algal stromatolites, stromatoporoids, trilobites, and conodonts. Age is Late Ordovician.
