Pg. 715. Doyle shale in Chase stage. Variously colored shales, 60 feet thick, including a few thin beds of soft limestone. Overlies Fort Riley limestone and underlies Winfield formation, which includes (descending) Winfield concretionary limestone; yellowish shales; and cherty limestone ("Marion flint"). Age is Permian (of Prosser and Frech). [This definition of Doyle shale was followed until 1929.]

Doyle formation of Chase group. Divided Doyle shale of Prosser into 3 members (descending) Gage shale, Towanda limestone, and Holmesville shale, aggregating 66 feet in thickness, and divided overlying Winfield [formation], also of Chase group, into 3 members (descending): Cresswell limestone (called "concretionary" limestone in previous reports), Grant shale, and Stovall limestone. Age is Permian (Big Blue).

These recent reports [1929-1936] (which apparently follow Prosser's definitions of Doyle and Winfield) have not been considered by the USGS for its publications.

Pg. 80. Doyle shale of Chase group. Restored to formal nomenclature and considered as consisting of (ascending) Holmesville shale, Towanda limestone, and Gage shale members, which had heretofore been given formational rank. Overlies Barneston limestone; underlies Winfield limestone. Age is Permian.

Pg. 115-116. Doyle shale of Chase group. Subdivided into (ascending) Holmesville shale, Towanda limestone, and Gage shale members. Members recognized in Kansas, southeastern Nebraska, and northern Oklahoma where they have been identified in Kay and Osage Counties. Members cannot be differentiated in Pawnee County. Thickness 103 to 118 feet in Kay County; 125 to 135 feet in Osage County. Thickness difficult to determine in Pawnee County; electric logs show about 150 feet. Overlies Fort Riley limestone; underlies Winfield limestone. Age is Early Permian (Wolfcamp).
