Lithological description

Coarse-grained to conglomeratic sandstones with pebbles of quartz, sandstone and limestone. It frequently contains clay flakes, clay-ironstones and some coals embedded in an argillaceous, very glauconitic sandstone. Medium-grained sandstones, often with a high content of calcareous cement, occur as well, and grade locally into calcareous sandstones. In some localities a high content of sponge spicules is characteristic.

Depositional setting

Inner- to middle-neritic, locally coastal, setting, in prograding offshore-shoals and coastal-barrier systems.

Definition of lower boundary

Conformably covers the Westerbork Member.

Definition of upper boundary

(mildly un-)Conformably overlain by the main Vlieland Claystone member. Can also be unconformably overlain by the Holland Formation.
