Summary:

Wildwood Member of Kirkwood Formation. Clay, silty, massive to finely bedded, dark-gray to olive-gray, locally interbedded with thin beds of light-colored sand. Upper beds more sandy than lower beds but also contain many thin to thick beds of clay. Thickness up to about 59 feet (18 m). Geophysical logs indicate this unit is characterized by shifting patterns of clay and sand with clay at base and sand at top; thickness in subsurface 262+ feet (80+ m). Overlies Shiloh Marl Member of Kirwood, contact is sharp and unconformable. Fossils. Diatoms of the East Coast Diatom Zone 2 of Andrews, 1988 (USGS Prof. Paper 1481).
