Name Origin
The Abingdon Coal Member of the Spoon Formation (Culver, 1925, p. 75) is named for Abingdon, Knox County.
Type Section
Abingdon is near the type locality (cen. 6, 9N-2E) (Weller et al., 1942b, p. 1589).
Correlation
Although the Abingdon is not definitely recognized in other parts of the state, coals locally present near this position in northern and southern Illinois may be equivalent to the Abingdon Coal.
Extent and Thickness
The Abingdon is recognized only in western Illinois, where it varies in thickness but only locally exceeds 2 feet. It is absent from extensive areas.
