Springer member, basal member of Glenn formation. Largely black and blue shales separated by thin beds of sandstone and limestone. The shales at base are black and soft. Near top blue predominates, but there are some of black shale several feet thick. To north of Ardmore it contains no calcareous members, but there are 12 brownish or drab sandstones ranging in thickness from a few feet to 100+ feet, some of which grade into shales to south and east. Around Criner Hills sandstones are less important and numerous beds of tin brownish limestones occur. Thickness 4,000 to 6,000 feet. Fossiliferous (brachiopods, bryozoans, bivalves, cidaroids). Rests conformably on Carboniferous Caney shale and underlies Otterville limestone member (new) of Glenn formation. Age is Pennsylvanian. Report includes geologic map, structural map, cross sections, fossils listed.
Town of Springer [Carter Co., central southern OK] is in midst of this member.

Pg. 331-347. Goldston's [1922] Springer member seems to us to include both pre-Glenn and post-Glenn beds. We are satisfied Springer beds were excluded from Glenn formation as originally defined, and that they are part of Caney shale; in places they probably included the Hoxbar.

Raised in rank to formation. Was formerly included as basal member of the Glenn formation (Goldston, 1922). Is seen in the Ardmore basin in southern OK, S. Oklahoma folded belt province. Type area is at the village of Springer in Carter Co, OK. Consists of 3,000-3,500 ft of black bituminous shales with ferruginous and calcareous concretions, interspersed with four conspicuous persistent sandstone members. Divided into the following newly named members (ascending): Rod Club sandy, Overbrook sandstone, Lake Ardmore sandstone, and Primrose. The sandstone members are separated from each other by black bituminous shale with ferruginous and calcareous concretions, all unnamed parts of the Springer. Overlies Caney shale; underlies Jolliff member (new) of Dornick Hills formation (new). Rod Club at base of Springer is the lowest Carboniferous sandstone known in the Ardmore basin. The upper contact of Springer placed at base of lowest fossiliferous Pennsylvanian limestone. Fossil list; geologic map; columnar section. "Regarded as of earliest Pennsylvanian age."
