Summary:
Pg. 41. Barneston formation of Chase group. Erected to include Florence flint and Fort Riley limestone, which are in contact, except at a few places where a thin shale intervenes. The Florence or lower member is distinguished from the Fort Riley by its abundant chert content. The members are usually mapped together as Fort Riley-Florence. Their average combined thickness from southern Kansas to Nebraska is 50 feet or more. They constitute a strong formation which produces bold round escarpments. Occurs below Doyle formation and above Matfield formation, both of Chase group. Age is Permian (Big Blue).
Type locality: in bluffs west and southwest of Barneston, Gage Co., southeastern NE.

Summary:
(Paleozoic Era; Permian System by H.G. O'Connor, D.E. Zeller, C.K. Bayne, J.M Jewett, and Ada Swineford, p. 48.) Barneston Limestone of Chase Group. In Kansas, comprises two thick limestone members separated by a thin shale member [Florence Limestone Member, Oketo Shale Member, Fort Riley Limestone Member]. Caps much of the western part of the Flint Hills. The upper limestone [Fort Riley] makes an extensive dip slope and crops out as a steep escarpment that extends north to south across eastern Kansas. Thickness about 80 to 90 feet. Occurs above Blue Springs Shale Member of Matfield Shale and below Holmesville Shale Member of Doyle Shale, both of Chase Group. Age is Early Permian; Gearyan Provincial Stage (of H.G. O'Connor, 1963, AAPG Bull., v. 47, p. 1873-1877).
