==Lithology==<br />
The Canton is a gray, rather uniform shale that tends to be decidedly silty in its upper part. In western and northern Illinois, where it is primarily recognized and is as much as 50 feet thick, the lower few feet is dark gray and contains a varied marine fauna and several layers of fossiliferous, calcareous coneretions. In northern Illinois a 4-6 inch bed of canneloid coal occurs locally about 10 feet above the base of the Canton. In central and western Illinois, from south of Springfield to the vicinity of Du Quoin in Perry County, the interval between the Herrin (No. 6) and Springfield-Harrisburg (No. 5) Coals thins, and the Canton Shale is only a foot or so thick or is absent. <br />

==Age and correlation==<br />
In southern Illinois the shale above the St. David Limestone and the shale either immediately or a few feet above the Briar Hill Coal may be in part equivalent to the Canton.<br />
