Historical:Livingston Limestone Member
M. E. Hopkins and J. A. Simon
The Livingston Limestone Member of the Bond Formation (Worthen, 1875, p. 11-19), the top of which forms the top of the formation in eastern Illinois, is named for Livingston, Clark County.
The type section consists of exposures along Big Creek, about 2 miles northwest of Livingston (SE NW 6, 11N-11W) (Wanless, 1956, p. 12).
The Livingston is correlated with the Millersville Limestone west of the La Salle Anticlinal Belt.
Extent and Thickness
The Livingston occurs in two or three benches separated by shale beds 1-6 feet thick and has a maximum thickness of about 25 feet. The Livingston is well developed in Vermilion, Edgar, Clark, and eastern Coles Counties, where it has been extensively quarried. It thins southward into Crawford County.
It is generally fine grained and medium to thick bedded, and each bench thins to the south as the shale partings become thicker.
