Greyish brown medium to very coarse sand, gravelly, micaceous, pink and multi-coloured sand and gravel components, unstable heavy minerals, fining northwestward. Grey to bluish grey clay, silty, local sand lamination. Subordinate lags of greyish brown to reddish multi-coloured granules and pebbles.
Braided and meandering fluvial (Rhine and Meuse), including channel, bar, cut-off meander, oxbow lake and crevasse.
Commonly marked by a lag deposit, and In its southern range by reddish brown precipitation of iron hydroxides. Unconformable, generally sharp contact with paler and finer (more clayey) fluvial sand (Appelscha, Stramproy, Peize and Waalre Formations) or with finer pre-Quaternary units (fluvial Kieseloolite Formation and various marine units).
Unconformable, commonly sharp contact with paler, coarser and more gravelly fluvial sand (Beegden, Urk and Kreftenheye Formations), heterogeneous glacial sediment (Drente Formation), shelly marine sand (Eem Formation), much finer periglacial sand (Boxtel Formation) or ice-pushed units. Locally, the transition into the Urk and Kreftenheye Formations is diffuse.
