Name Origin

The Vermilionville Sandstone Member of the Carbondale Formation (Cady, 1915, p. 29) is named for Vermilionville, La Salle County.

Type Section

The type locality is west of the village of Vermilionville, along the Vermilion River (SE 9, 32N-2E) (Wanless, 1956, p. 10).

Other Names

The Vermilionville was formerly called Cuba Sandstone in western Illinois (Savage, 1927) and Waupecan Sandstone in northeastern Illinois (Culver, 1922a).

Stratigraphic Position

It is well developed in northern and western Illinois, where it occurs in the interval between the Herrin (No. 6) and the Springfield (No. 5) Coals. It is probably present in southern Illinois, where three sandstone units, all of which locally occur in channels, are present in this interval. One sandstone is below the Herrin Coal, another is below the Briar Hill (No. 5A) Coal, and a third is associated with the Dykersburg Shale. The Vermilionville is generally overlain by a few feet of the Big Creek Shale and is underlain by the Canton Shale.


The Vermilionville is an argillaceous to silty, fine-grained sandstone that in places occupies channels cut into the underlying strata. In such channels it is as much as 80 feet thick.
