The Millersville Limestone Member of the Bond Formation (Taylor and Cady, 1944, p. 22).
Named for Millersville, Christian County.
The type locality consists of exposures near the village (SE NE 28 and NW NW 31, 12N-1W) (Payne and Cady, 1944, p.12-13).
The the top of the Millersville Limestone Member defines the top of the Bond Formation in central and southern Illinois.
In the type area the Millersville is 50 feet thick and is divided into two or three benches by shale partings as much as 2-3 feet thick. It is the thickest limestone in the Pennsylvanian System in Illinois. In southern Fayette, Effingham, and Jasper Counties and farther south it is not well developed, although thin limestones in that area are considered as correlatives of part of the Millersville.
The limestone is light gray and fine grained. The Millersville has been extensively quarried in central Illinois.
The Millersville contains a diversified open-marine fauna.
East of the La Salle Anticlinal Belt, the Livingston Limestone is correlated with the Millersville, as is the Argentine Limestone Member of Missouri.
