Name Origin

The Manley Coal Member of the Abbott Formation (Kosanke et al., 1960, p. 31) is named for Manley, Fulton County.

Type Section

The Manley shares the type locality of the Babylon Sandstone Member (Wanless, 1957, p. 66, 205).

Other Names

The Manley Coal was previously called the Babylon Coal (Wanless, 1931a, p. 189-190, 192-193).


It is correlated with the Shady Lane Coal Member of Indiana.

Extent and Thickness

The Manley Coal is widely distributed in western Illinois but occurs sporadically. It ranges up to 4 feet thick and has been mined in a few places. The Manley has not been identified in southern Illinois.


It varies from banded coal to cannel coal, and at one mine in Fulton County cannel coal 2.5-3 feet thick was once mined (Wanless, 1957).
