Pg. 51. Cresswell limestone. Top member of Winfield formation of Chase group. Has been called the "concretionary limestone." Persists from Nebraska to Oklahoma in thickness of 4 to 11 feet. Is solid massive limestone at most points in southern Kansas, but northward from there it carries large concretions, a small amount of chert, and at most places is interrupted by a thin shale near middle. Becomes less massive and non-concretionary in its northern occurrence. Overlies Grant shale member of Winfield formation and underlies Luta limestone in central and southern Kansas. The Luta probably does not extend to Nebraska, where Odell shale member of Enterprise shale overlies Cresswell limestone. [On p. 56 Luta limestone is included in Marion formation. On p. 57-58 Condra says:] The Luta limestone is thought not to extend to northern Kansas and Nebraska, but it is possible that part of lower gray zone of Odell shale member of Enterprise shale in this area may be correlative with it in age and thus represent a shale-mudstone facies of its development. The Luta has a thickness of 7 feet or more in central and southern Kansas, reaching 18 feet or more at a few places. It appears that some authors have assigned too great a thickness to the Luta in various exposures by including part of Cresswell limestone, and we find its thickness at type locality not as great as given by Dr. Beede. There is a small deformation at type locality and Luta-Winfield contact is not very definite. Whether the Luta should be correlated with the Winfield or with the Marion has not been determined to full satisfaction of all geologists concerned, nor is it agreed that it is not a zone of Cresswell limestone. It seems, however, that it was developed in the cycle which produced the Cresswell, in which deposition changed from lime to lime and shale, becoming more shaly at top as a transition to lower zone of Odell shale. It also appears that faunal content is not markedly different from that of Winfield formation. Age is Permian.
Type locality: on east side of golf course, in NE/4 sec. 18, T. 34 S., R. 4 E., north side of east edge of Arkansas City. Named from Cresswell Twp., Cowley Co., eastern KS.

Pg. 12. Cresswell limestone, [2nd from top member of Winfield limestone of Chase group]. Treated Luta limestone as top member of Winfield limestone. This change has not yet been considered by the USGS for its publications. Age is Permian.

Pg. 44. Cresswell limestone member of Winfield formation of Chase group. Consists of limestone and locally shale in upper and middle parts and massive fossiliferous limestone in lower part; upper part, which has been called "Luta limestone" is thinner bedded and more shaly. Throughout a considerable distance, the lower massive ledge is almost constantly 3 feet thick. Total thickness of member commonly about 17 feet. Overlies Grant shale member; underlies Odell shale. Age is Early Permian (Wolfcampian).
