Bentheim Sandstone Member

Formal (NAM & RGD 1980). Amended (Van Adrichem Boogaert & Kouwe 1993).
Lithological description

Generally fairly thick sequence of massive sandstones, calcareous, with abundant shell fragments, lignite particles and glauconite grains. Grain sizes predominantly range from fine to medium sand, but up to granule sizes occur. Bioturbation is common.

Depositional setting

Coastal (deltaic) to marine (inner- to middle-neritic) setting, in prograding offshore-shoals and coastal-barrier systems.

Definition of lower boundary

Locally, the Bentheim Claystone Member below is absent, bringing the Bentheim Sandstone Member in unconformable contact with the Coevorden Formation (Niedersachsen Group). Usually conformably undelain by the Vlieland Claystone Formation (Bentheim Claystone Member).

Definition of upper boundary

Usually conformably overlain by the Vlieland Claystone Formation (Ruinen Member). In salt-structure and basin-fringe-related settings the Bentheim Sandstone Member can be overlain unconformably by the Holland Formation or the Lower North Sea Group.
