Historical:Flat Creek Coal Member
M. E. Hopkins and J. A. Simon
The Flat Creek Coal Member of the Bond Formation (Simon, in Wanless, 1955, p. 1764) is named for Flat Creek in Bond County.
The type section is exposed along Flat Creek (NE SE 24, 6N-5W) (Kosanke et al., 1960, p. 39).
It is correlated with the Flannigan Coal of southeastern and eastern Illinois and the Fairbanks Coal Member of Indiana.
Extent and Thickness
The Flat Creek is a thin, widespread coal readily recognized on geophysical logs in southwestern Illinois.
The coal is widely overlain by a thin black shale and a marine limestone.
