Definition Hard and soft, mainly grey-white to yellow-brown, argillaceous marl with many burrows and yellow concretions. The lowermost beds generally consist of dark green marly clay.
Upper Boundary The upper boundary is a more gradual transition to the Landen Clay Member, which is expressed on gamma-ray logs by higher readings for the Landen Clay Member. On resistivity logs the marl can be very clearly distinguished by higher readings than the overlying Landen Clay Member.
Lower Boundary The lower boundary is formed by the sharp transition to the sands of the Heers Member, with relatively low gamma-ray readings.
Distribution The member is present in the provinces of Noord-Brabant and the northern part of Limburg, northern Flevoland and the northern part of Gelderland.
Age Late Paleocene (Thanetian). The foraminiferal assemblages belong to the FJ-Zone and are characterised by the presence of Trochammina inflata. Nannofossils are virtually absent.
Depositional Setting Probably shallow open marine.
Sequence Stratigraphy The unit seems to correspond with the Transgressive systems tract of cycle TA 2.1.
