|Name||Mt. Laurel Formation|
|Geologic age||Upper Cretaceous, upper Campanian|
Unconsolidated > Coarse-detrital > Sand (Bed)Sand, quartz, massive to crudely bedded, typically coarsens upward, interbedded with thin clay beds. Glauconite and feldspar are minor sand constituents. Muscovite and biotite are abundant near the base. Lower part of formation is a fine- to medium-grained, clayey, dark-gray, glauconitic (maximum 25 percent) quartz sand. Typically weathers to white or light yellow and locally stained orange brown by iron oxides.
Unconsolidated > Coarse-detrital > Gravel (Bed)Granules and gravel are abundant in the upper 1.5 m (5 ft).
Unconsolidated > Fine-detrital > Clay (Bed)interbedded with thin clay beds; locally, has small, rounded siderite concretions in the interbedded clay-sand sequence
