SKWF
Status
Formal (NAM & RGD 1980). Amended (Van Adrichem Boogaert & Kouwe 1993).
Lithologische beschrijving

On relative swells, it consists of basal, generally coarse-sandy to conglomeratic clastics, followed by light- to dark-grey, anhydritic, marly claystones with limestone intercalations. In the basinal lows intercalated halite beds occur. Further towards the western and northern margins of the Lower Saxony Basin, the basal clastics lose their prominent character, while the evaporite intercalations shale out.

Afzettingsmilieu

Restricted lacustrine basin-margin to marginal-marine sub-basin (lagoonal) setting, grading into floodplain to fluvial-plain setting along the extreme basin-fringe. Estuarine basin circulation favoured the periodic formation of evaporites.

Definitie ondergrens

Unconformably overlies the Altena Group or older sediments.

Definitie bovengrens

Characteristic wire-line log marker, corresponding to conspicuous claystone transition in the clayey-marly interval with fossiliferous limestones (top Serpulite Member).

Up to 289 m (DRO-01).
