NMTOKL
Status
Formal (Kuyl 1975).
Lithological description
Clayey sands, coarsening upward into very fine-grained (105-150 µm), micaceous sands with a low glauconite content. Locally, a thin layer of flat rounded flint pebbles is found at the base. Calcareous fossils are scarce and the sands are locally lithified. The top of the sands shows an orange or purple staining, interpreted as the result of emergence and soil development.
Depositional setting
Shallow-marine environment.
Definition of lower boundary
Unconformably overlies the Landen Formation or older deposits.
Definition of upper boundary
Sharp and conformable with the overlying Goudsberg Member.
Thickness indication
Up to 71 m (SM-39/B60D0266).

Restricted to southern Limburg
