Extent and thickness
Lithology
The Hanover is a thin marine limestone that is seldom more than 4 feet thick and in places is represented only by nodules of limestone or a thin concentration of marine fossils in which brachiopods are dominant. It is a persistent bed of gray, argillaceous, brecciated or nodular limestone in most of western and northern Illinois, where it overlies the black Excello Shale. It is poorly developed in southern Illinois.
