Name Origin

The Paint Creek Group (S. Weller, 1913, p. 120; Swann, 1963, p. 76) is named for Paint Creek, a stream in Randolph County.

Type Section

The type section of the Paint Creek Group is along a tributary west of McCuen School (E1/2 2, 5S-9W).

Extent and Thickness

The Paint Creek Group is recognized only in western Illinois.

Description

The Paint Creek Group is dominantly shale and limestone and consists of the Downeys Bluff, Bethel, and Ridenhower Formations (fig. M-25). Although the Bethel is normally a sandstone, it is shale in that area and includes a bed of bright red shale. The name was formerly used in southeastern Illinois for the strata now included in the Ridenhower Formation.
