==Name==
 
===Original description===
The Cardiff Coal Member of the Carbondale Formation (Cady, 1915). The name was not in general use until re-introduced by Peppers (1970).

Named for Cardiff, Livingston County.

==Stratigraphic relationships==
It generally is not more than 10 feet above the Colchester (No. 2) Coal. At a few localities the Cardiff directly overlies the Colchester Coal.
 
==Extent and thickness==
The Cardiff Coal is known only in northeastern Livingston, southeastern Grundy, and western Kankakee Counties, where it occurs in channels trending northeast-southwest eroded in gray shale. The Cardiff Coal is highly lenticular and was reported in one mine to be 12 feet thick.
 
==Lithology==
It commonly is in more than one major bench, the benches separated by gray shale. Peppers (1970) described the flora and concluded that the Cardiff Coal is a little older than the Lowell Coal.
