Carlinville limestone member of McLeansboro formation. According to G.H. Cady, 1921 (Illinois Geol. Survey Coop. Min. Ser., Bull. no. 26) and 1926 (Illinois State Acad. Sci. Trans., v. 19, p. 257, etc.), the Carlinville limestone lies 100+/- feet below Shoal Creek limestone and 20 to 60 feet above coal No. 8. E.W. Shaw, 1923 (USGS Carlyle-Centralia folio, No. 216), also identified Carlinville limestone as older than Shoal Creek limestone. According to Wallace Lee, 1928 (USGS Gillespie-Mount Olive folio, No. 220), the Carlinville limestone lies 53 to 81 feet below Shoal Creek limestone. H.R. Wanless, 1931 (GSA Bull., v. 42, no. 3, p. 804), placed Carlinville limestone nearly 100 feet below Shoal Creek limestone.
