Grey to yellowish brown, fine to very coarse sand, slightly to very gravelly, slightly micaceous, non-calcareous (in ice-pushed ridges) to calcareous, with plant remains (including wood), with augite and abundant pink minerals.. Subordinate clay layers, very sandy or silty and locally organic. Fine to very coarse gravel characterised by grey, brown, green and red sandstones and white quartz.
Fluvial (Rhine, sediment source in the mountainous hinterland of central and southern Germany). Northward, transition into estuarine, tidal and shallow marine.
Locally, marked by an up to 3-m-thick clay bed (Zandstra 1971; Bosch 1990). Elsewhere, sharp and unconformable contact with greyer, finer, less glauconitic and less calcareous fluvial sand (Appelscha and Peize formations) or with finer, more micaceous, more organic and less multi-coloured fluvioglacial sand (Peelo Formation). Gradual transition into slightly finer, more clayey and more micaceous fluvial sand (Sterksel and Waalre formations) or into less multi-coloured periglacial sand (Drachten Formation).
Locally exposed at the surface. Elsewhere, sharp and unconformable contact with finer, more micaceous, more organic and less multi-coloured fluvioglacial sand (Peelo Formation). Gradual transition into finer periglacial sand (Drachten Formation). Diffuse transition into gravelly glaciofluvial sand (Schaarsbergen Member, Drente Formation), or into gravelly fluvial sand (Kreftenheye Formation), except where separated by a coarse channel lag.
