Status
Formal (NAM & RGD 1980). Amended (Van Adrichem Boogaert & Kouwe 1993).
Lithological description
Alternation of dolomitic and/or anhydritic claystones, anhydrites, halites and limestones. Over synsedimentary highs, the halite layers thin and disappear, accompanied by a marked decrease of the anhydrite content.
Depositional setting
Highly-restricted lacustrine basin-margin to marginal-marine sub-basin setting. Evaporites can be attributed to a combination of estuarine basin circulation and reworking of outcropping Triassic and Zechstein evaporites.
Definition of lower boundary
Conformably rests on the variegated Weiteveen Basal Clastic Member, or unconformably overlies the Altena Group or older sediments. The base is placed at the lowermost carbonate or anhydrite bed.
Definition of upper boundary
Placed at a marked increase in GR-log readings and a drop in resistivity log readings, caused by the higher clay content of the Weiteveen Lower Marl Member.
Thickness indication
Generally less than 60 m and up to 96 m in SCH-197.
Geographical distribution
Regional correlation
UK: ?; GER: Münder Formation; BEL: -.
Origin of name
Named after the village of Weiteveen, municipality of Schoonebeek, in the southeastern part of the province of Drente.
