Summary:

Pg. 61-62. West Franklin limestone. Fossiliferous calcareous shale and black limestone, 2 to 25 feet thick, in Coal Measures of Posey County, southwestern Indiana. Overlain by either thin-bedded limestone or thin-bedded schistose sandstone, and underlain by argillaceous shale. [Age is Pennsylvanian.]
[Named from exposures at West Franklin, Posey Co., southwestern IN, according to C.A. Malott, 1929.]

Oil field located where Pike, Gibson, and Warrick Counties join, in secs. 7, 8, 9, 15, 16, and 17, T. 3 S., R. 8 W., [Oakland City and Lynnville 7.5-min quadrangles], southwestern IN.

Summary:

West Franklin formation. Consists of (descending): (1) dense gray crystalline limestone about 3 feet thick, rarely brecciated; (2) shale, 25 feet maximum; (3) hard blue to gray brecciated limestone, 5+/- feet. Consistently occurs 280 to 315 feet above coal V. Overlain by 0 to 30 feet of shale and sandstone which unconformably underlies Merom sandstone. Is same as Somerville limestone [of Fuller, 1902, 1904] and has priority. Age is Pennsylvanian (post-Allegheny).

Summary:

Pg. 126 (fig. 1), 128. West Franklin limestone. Only upper part of formation, a fossiliferous bed about 2 feet thick, is exposed in bed of small creek 3 mi east of Hazelton, in NE/4 sec. 26, T. 1 N., R. 10 W., [Union 7.5-min quadrangle, Gibson Co., IN]. South of Patoka River, it is a well known double bed of limestone about 200 feet above the Millersburg coal (coal VII). Underlies Ditney formation. Age is Pennsylvanian.
[Author states name West Franklin limestone was first applied to excellent exposures in bluff of Ohio River at West Franklin in southeast corner of Posey County, Indiana, by Leo Lesquereux, 1862, IN Richard Owen, Report of a geological recconoissance of Indiana, p. 294, [296]-297, and later it was used by John Collett, 1884, IN Indiana Dept. Geol. Nat. Hist. Ann. Rpt., no. 13, p. 61-62.]
