Stratigraphic relationships[edit | edit source]

The Mincke Member is the lower member of the Kings Lake Formation.

Extent and thickness[edit | edit source]

In Illinois the Mincke Member is exposed only near West Point Landing, Calhoun County. The Mincke Member thins northward from the type section to 4.9 feet in the Kings Lake type section and 3.6 feet at New London, Missouri.

Lithology[edit | edit source]

The Mincke Member consists of interbedded 1-5 inch beds of (1) silty argillaceous limestone that locally contains a small amount of fine sand, (2) very fossiliferous calcarenite, and (3) green to brown shale. A bed of yellow bentonite 0.5-2 inches thick is persistent in a bed of brown shale 1-1.5 feet below the top.
