Banzet Formation of the Cherokee Group. The interval of shales, siltstones, thin limestones, thin coals, and lenticular, discontinuous sandstones found in repetitive sequences between the top of the Ardmore Limestone and the base of the Excello Shale in southeastern Kansas and northeastern Oklahoma is here named the Banzet Formation of the Cherokee Group. Includes the Bevier, Lagonda, and Mulky Members, here reduced from formation rank, and the Bevier coal bed in the Bevier Member, the Iron Post coal bed in the Lagonda Member, and the Kinnison Shale Bed, Breezy Hill Limestone Bed, and Mulky coal bed in the Mulky Member. The Kinnison and Breezy Hill are reduced from members of the Mulky Formation. Age is Middle Pennsylvanian (Desmoinesian).
Type area: 11,000 sq mi between T. 26 S. (KS) and T. 22 N. (OK), and between R. 2 E. and R. 23 E. Origin of name not stated by author.

Pg. 7+. /Banzet formation (informal) of Cherokee Group. Presents an informal classification for upper part of Cherokee Group of eastern Kansas and northeastern Oklahoma; revised from Krumme (Oklahoma Geol. Survey Bull., no. 131, 1981) and Denesen (1985). [Term "Formation" is applied to formal nomenclature (CSN, 1933; ACSN, 1961, 1970; NACSN, 1983, 2005, 2021).]
At "type section" [reference section], upper part of Banzet includes (descending) informal Breezy Hill limestone and Iron Post coal beds. In eastern Kansas, the Banzet is informally subdivided into (descending): (1) Mulky member, includes Mulky coal bed at top, Breezy Hill limestone bed, and Kinnison shale bed at base; (2) Lagonda member, top = Iron Post coal bed; and (3) Bevier member, top = Bevier coal bed. Lies above informal /Verdigris formation of Cherokee Group and below Fort Scott Limestone of Marmaton Group. Fossils. Age is Middle Pennsylvanian (Desmoinesian).

[†Banzet Formation of Cherokee Group not adopted by the OK and KS Geol. Surveys. In Oklahoma, rocks included in (descending) Wetumka Shale, Calvin Sandstone, and Senora Formation (see Fay, 1997, Oklahoma Geol. Survey OFR-2-97). In Kansas, rocks included in Cabaniss Formation (see Kansas stratigraphic chart, 2010, updated from Kansas Geol. Survey Bull. no. 189).]
