Stratigraphic relationships
The sandstone occurs above the Chapel (No. 8) Coal and below the Womac Coal (Andresen, 1961).
Extent and thickness
It is known primarily in eastern Illinois, but it was reported by Andresen to split into two distinct sandstones in southwestern Illinois, the lower unit occurring below the Carlinville Limestone. The Inglefield Sandstone locally exceeds 80 feet in channels oriented south-southwest, but it is relatively widespread as a much thinner sheet sandstone in most of the Illinois Basin.
