Historical:Seelyville Coal Member
M. E. Hopkins and J. A. Simon
The Seelyville Coal Member of the Spoon Formation (Kosanke et al., 1960, p. 33; incorrectly spelled "Seeleyville") is named for Seelyville, Vigo County, Indiana.
The type locality is in mines in Seelyville (12N-7 and 8W).
It was originally named Indiana Coal III (Ashley, 1899, p. 106-107) but informally called Seelyville in Indiana.
In Indiana it is now called Seelyville Coal Member (III).
Extent & Thickness
In Illinois the Seelyville is known primarily in Edgar, Clark, and Crawford Counties, where it as much as 6 feet thick. It occurs locally in southern Illinois between the De Koven and Colchester Coals.
