Extent and thickness

The Coffeen Limestone is less than 2 feet thick in the type area. It is 8 feet above the Witt Coal in the type area and may be fairly widespread, but it has been recognized only in the northern part of southwestern Illinois.





Well log characteristics


The Coffeen contains a varied marine fauna dominated by brachiopods, crinoids, and bryozoans.

Age and correlation

The Coffeen Limestone probably correlates with the Riverview Limestone Member, which lies about 40 feet above the Fairbanks Coal Member of Indiana.
