De Lier Member

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

Alternation of thin-bedded, very fine- to fine-grained argillaceous sandstones, generally glauconitic and lignitic, and sandy claystones, commonly glauconitic and with shell fragments and frequent bioturbation. Siderite concretions are common.

Depositional setting

Coastal to outer-neritic marine setting in a prograding coastal system.

Definition of lower boundary

Boundary with the Eemhaven Member or the main Vlieland Claystone Formation is a gradual transition. On the southern fringe of the West Netherlands Basin, the Eemhaven Member can be absent, and the member rests conformably upon the coastal/fluvial-plain deposits of the Nieuwerkerk Formation.

Definition of upper boundary

(Mildly un-)conformable upper boundary with the Lower Holland Marl Member is well-defined at the top of the sandstone.
