Grey to greyish white, yellowish brown to greyish green fine to very coarse sand, gravelly, (slightly) calcareous. Local channel fills (near the top) and horizontal stratification.
Fluvioglacial (including proglacial sandur; stratified sand), sub-/proglacial (tunnel valley, kame, esker), locally glaciolacustrine. Crystalline gravel and flint have a northern provenance, which may be masked by reworked fluvial gravel.
Generally diffuse transition into fluvial sand.
Sharp contact with till (Gieten Member, Drente Formation), gradual transition into fluvial sand (Kreftenheye Formation).
