Summary:

Chase adopted [ca. 1902] as group term, to include the following formations (descending): Winfield limestone, Doyle shale, Fort Riley limestone, Florence flint, Matfield shale, and Wreford limestone. This definition has been followed for many years by both Kansas Geol. Survey and USGS. In Sept. 1936, however, R.C. Moore (Kansas Geol. Soc. 10th Ann. Field Conf. Gdbk., p. 12) shifted the upper boundary to top of Luta limestone, which he treated as top member of Winfield limestone. This change has not yet [ca. 1938] been considered by USGS for its publications.

Summary:

Pg. 68-71; R.C. Moore and others, 1951, Kansas Geol. Survey Bull., no. 89, p. 41-45. Chase group.

In southern Kansas and northern Oklahoma, group consists of over 340 feet of red and green shales and persistent chert-bearing limestones. Southward, limestones thin and chert content diminishes abruptly. In Pawnee County, includes (ascending) Wreford limestone, Matfield shale, Fort Riley limestone, Doyle shale, and Winfield limestone. Wolfcamp series. South of Pawnee County, rocks of group grade laterally into Asher formation of central Oklahoma.
