Rijn Member

Formal (Van Adrichem Boogaert & Kouwe 1993).
Lithological description

White to greyish-orange sandstone, very fine-, rarely up to very coarse-grained, slightly calcareous, argillaceous, locally with abundant glauconite and mollusc shells. In general the interval is intensely bioturbated. Few intercalated thin beds of olive-grey, silty mudstone. On GR logs the member appears as a thick sequence with relatively high readings, resulting from the high clay- and glauconite-content. The member shows considerable variations in thickness.

Depositional setting

Offshore shoal-bars and/or transgressive sheet-sands.

Definition of lower boundary

Unconformably rests upon Triassic or Lower/Middle Jurassic sediments, or upon the lignitic heterolithics of the Delfland Subgroup (Nieuwerkerk or Breeveertien formations).

Definition of upper boundary

Upper boundary is well-defined at the top of the marine sandstone body.
