Summary:
Glenn formation. Friable blue shale, with thin brown sandstones and occasional thin limestones. Thickness estimated to be 1,000 to 3,000 feet. Overlies Caney shale and may include highest Carboniferous rocks exposed in Tishomingo quadrangle. Older than Franks conglomerate (new). Age is Carboniferous (Pennsylvanian) based on fossils.
Named from town of Glenn, Carter Co., central southern OK. Exposed in western part of Tishomingo quadrangle and to the west along southern edge of Arbuckle Mountains.

Summary:
Glenn formation of Ardmore basin divided into (descending) Hoxbar member, Deese member, Cup Coral member, Otterville limestone member, and Springer member. Total thickness 12,000 to 19,000 feet. Overlies Carboniferous Caney shales; underlies unnamed Carboniferous redbeds. Fossiliferous (brachiopods, bryozoans, mollusks, bivalves, gastropods, pelecypods, cephalopods, cidaroids). Age is Pennsylvanian. Exposed between Arbuckle Mountains to north and Criner Hills to south, in Carter and Love Counties, central southern Oklahoma. Report includes geologic map, structure map, cross sections, correlation chart, fossil lists.

Summary:
Pg. 331-347. We are convinced it was not Taff's intention to include in Glenn formation the beds called Hoxbar member by Goldston. Typical Glenn includes only Deese and "Cup Coral" members of Goldston. [For their views regarding Otterville and Springer members of Goldston see under Otterville and Springer.]

Summary:
Pg. 7-21. Recognized following units in Carter County, central southern Oklahoma (descending): Hoxbar formation, 4,000+/- feet; Deese formation, 5,000+/- feet; Dornick Hills formation 1,500 to 4,000 feet (including Otterville limestone, 25+/- feet thick, in lower part); and Springer formation, 3,000 or more feet thick.

Summary:
Springer formation was included in Glenn formation by Taff in Tishomingo folio, but was excluded from Glenn by Girty, Roundy, and Miser. Best solution is to drop it, as suggested by Gould (personal commun.).
