Mostly non-calcareous, slightly to very sandy. Local boulders up to 1.5 m diameter. Subordinate sandy loam and clay layers. Locally, loamy top layer is similar to the Wijchen Member (Kreftenheye Formation).

Fluvial (Meuse) sourced in the Ardennes and northeastern France.

Common coarse gravelly basal lag in Roer Valley Graben. Generally sharp contact with multi-coloured, micaceous and gravelly fluvial sand (Sterksel Formation).

Commonly exposed at the surface. In the central Netherlands, diffuse contact with fluvial Rhine deposits (Kreftenheye Formation). On the Peel Block and in the Roer Valley Graben, sharp contact with finer aeolian and local river sand (Boxtel Formation).

Up to about 40 m.
