Pg. 9. Towle shale formation of Admire group. About 2 to 2.5 feet of gray shale at top, 10 to 11 feet of red shale in middle, and 1+/- foot of gray shale at base. Total thickness 14+/- feet. Underlies Aspinwall limestone formation and overlies Brownville limestone formation. Basal formation of Admire group. Age is considered Permian (lower part of Big Blue).

Towle Shale Member of Onaga Shale of Admire Group. Overlies Brownville Limestone Member of Wood Siding Formation and underlies Aspinwall Limestone Member of Onaga. Consists of shale, mudstone (paleosols), and some limestone; locally includes fossiliferous shale or mudstone at base. Contains brachiopods and ADETOGNATHUS conodonts. Interpreted to be nearshore marine deposits. Age is Late Pennsylvanian (late Gzhelian; STREPTOGNATHODUS BELLUS conodont zone), based on stratigraphic position.
Described from measured sections in Chautauqua, Greenwood, Pottawatomie, and Wabaunsee Counties, eastern Kansas, and Osage County, northern Oklahoma. (Locs. 1, 2, 3, A2, A12, A15, A20.)
