Cooper, C.L., 1931, [Geologic map of Arbuckle Mountains, central southern Oklahoma], IN Decker, C.E., and Merritt, C.A., The stratigraphy and physical characteristics of the Simpson group: Oklahoma Geological Survey Bulletin, no. 55, pl. 1.


Summary:

Map of Arbuckle Mountains shows: (1) in southwestern part of mountains, Sycamore limestone overlain by Caney shale and underlain by Woodford formation; (2) in southeastern part of mountains, Caney shale resting on Woodford formation; and (3) in northeastern part of mountains, Welden limestone overlain by Caney shale and underlain by Woodford formation. In latter area Welden Creek cuts across his Welden limestone. [According to G.H. Girty (personal communication) the faunas of typical Sycamore limestone and Cooper's Welden limestone differ. The bulletin cited above is devoted to stratigraphic and physical characteristics of Simpson group, and the text does not mention Welden limestone.]

Summary:

Table on p. 579 showed the Mississippian of Hunton arch area divided into (descending) Lower Caney, Welden, and Woodford; and on map on p. 583 of his paper, which is "after Geo. D. Morgan," appears Welden limestone (Sycamore).

Summary:

On p. 954 showed the following downward succession of formations in Fitts oil pool, Pontotoc County, Oklahoma: Pennsylvanian Caney, Mississippian Caney, Mayes, Welden, and Woodford. On p. 958 he treated Mayes and Welden as part of "Mississippian Caney," and stated that the Welden consists of 5 to 10 feet of grayish white, finely crystalline limestone.
