Lithologische beschrijving

Bluish grey, limestone-rich claystone interval which is characterised by the dominant occurrence of serpulid fragments. The frequently intercalated microcoquina beds and laminae contain abundant pelecypod and ostracod remains. Anhydritic beds and nodules are abundant.

Afzettingsmilieu

Lacustrine basin-margin to marginal-marine sub-basin (lagoonal) setting. With low input of clastic material.

Definitie ondergrens

Usually conformably overlies the Weiteveen Upper Marl Member, but locally unconformably overlies the Altena Group or older sediments.

Definitie bovengrens

Marked by characteristic wire-line log marker, corresponding to conspicuous claystone break in the clayey-marly interval with limestones.
