Definition This unit consists of stacked, small-scale fining-upwards cycles of fine-grained sandstone, siltstone, and claystone. Oolite beds may be intercalated. It commonly displays reddish to greenish colours. A number of claystone beds yield anomalously high readings on the gamma-ray log, which are very suitable for correlation purposes. The overall trend of this member is coarsening upwards. The unit grades laterally into the sandstones of the Lower and Upper Volpriehausen Sandstone Members. .
Subdivision A distinct sandstone bed, which can be distinguished in the western and northern offshore, is informally named the Volpriehausen Avicula sandstone bed. This bed is known in Germany as the Göldsandstein (Röhling (1991) ). In well L02-01 (see pdf) it was found at 4078 - 4085 m below rt. The interval between the base of this sandstone bed and the base of the Detfurth Formation can be informally referred to as the Volpriehausen Avicula member (RBMVA).
