Pg. 18, 69, 71-72. Hickory Creek shale member of Plattsburg limestone of Lansing group. Plattsburg limestone divided into 3 members (descending): Spring Hill limestone member, Hickory Creek shale member, and Merriam limestone member. The Hickory Creek shale member consists of 1+/- feet of black carbonaceous shale, which to south becomes gray or yellowish and argillaceous. Locally absent, and 0.5 mi east of De Soto thickens to 20 feet. In some instances, as at south edge of sec. 29, T. 13 S., R. 23 E., the shale is overlain and underlain by a peculiar ochery, shaly limestone or calcareous shale. In such case, for convenience, the yellowish shaly layer is considered the division between the upper and lower Plattsburg. Age is Late Pennsylvanian (Missouri age).
Named from Hickory Creek near Peoria, Franklin Co., eastern KS.
