Summary:

Scranton shale is still [ca. 1938] applied by Nebraska Geol. Survey and the USGS to the beds underlying Burlingame limestone and overlying Howard limestone, but R.C. Moore in 1936 (Kansas Geol. Survey Bull., no. 22) discarded the name from the Kansas classification, treating the named subdivisions into which Condra had in 1930 divided it as formations in Wabaunsee group. Moore stated (p. 210) that Rock Lake shale, South Bend limestone, Plattford shale, and Cass limestone of Condra do not belong to Scranton shale. Condra in 1930 transferred his Rock Lake shale and South Bend limestone to Stanton limestone, and in 1935 stated (Nebraska Geol. Survey Paper, no. 8) his Plattford shale is same as Weston shale, but did not explain what replaces his Cass limestone, although he abandoned that name in 1930.

Summary:

Pg. 2274 (fig. 1), 2277. Scranton shale reintroduced as a formation with same stratigraphic span assigned originally to it by Haworth and Bennett. Consists predominantly of shale but contains some thin limestones and shaly sandstones. Comprises upper half of Sac-Fox subgroup [informal] of Wabaunsee group; includes strata between Bern limestone (new) above and Howard limestone below. Thickness about 125 feet. Includes (ascending) White Cloud shale, Happy Hollow limestone, Cedar Vale shale, Rulo limestone, and Silver Lake shale members. Age is Late Pennsylvanian (Virgilian). Reference section proposed.
Reference section: exposures along eastward-flowing stream extending through middle part of sec. 34, T. 12 S., R. 15 E., Shawnee Co., eastern KS.
["Subgroup" not recognized as a formal stratigraphic rank term (CSN, 1933; ACSN, 1961, 1970; NACSN, 1983, 2005, 2021). Considered informal and should not be capitalized.]
