|Geologic age||Upper Cretaceous, lower Campanian|
Unconsolidated > Fine-detrital > Clay (Bed)locally interbedded with thin to thick beds of dark clay. Abundant carbonaceous matter, with large lignitized logs occur locally, especially in clay strata.
Unconsolidated > Coarse-detrital > Sand (Bed)Sand, quartz, fine- to coarsegrained, gravelly, massive, bioturbated, medium- to dark-gray; weathers light brown, yellow, or reddish brown, locally interbedded with thin to thick beds of dark clay. Feldspar, glauconite, and muscovite are minor sand constituents. Sand is extensively trough crossbedded particularly west of Mount Holly, Burlington County. Lowest part of unit is a massive sand that contains small to large, soft, light-gray siderite concretions.
