Abstract
The Nimtz Quarry Section provides evidence for the separation of key rock-stratigraphic units in northern Illinois. Although field evidence is lacking for separation of the Argyle and Nimtz Till Members at the quarry, the underlying Nimtz Till is identified by its illite percentage, which is higher than that of the Argyle Till. Evidence at the quarry suggests that the two diamictons may represent the same ice advance. The Oregon, Belvidere, Herbert, and Kellerville Tills may also be present at the quarry. -from Authors
