Nassawadox Formation: Occohannock Member

Occohannock Member (Mixon, 1985). Light-yellowish-gray, fine to medium sand underlying southwest-sloping terrace (altitude 30-18 feet) on west side of upland. Sand is dominantly massive to horizontally bedded, but shows some small-scale cross-bedding; locally contains clay and silt as matrix and thin beds. Unit was deposited in a low-energy, open-bay environment. Thickness ranges from a featheredge near bay-facing scarp along western margin of upland to 20 feet in downdip areas near present bay.
