Stratigraphic relationships
The Babylon Sandstone Member is the lowest named member of the Abbott Formation in western Illinois. In many places it is the lowest unit of the Pennsylvanian System and unconformably overlies Mississippian limestones.
Extent and thickness
The Babylon Sandstone is widely present in western Illinois and at its maximum is about 25 feet thick. The Babylon in western Illinois becomes thinner and sporadic in occurrence to the south.
Lithology
The sandstone is made up of relatively pure, subangular, medium to coarse quartz grains, most of which have been secondarily enlarged by quartz overgrowths that sparkle in sunlight (Wanless, 1957).
