Formal (Van Adrichem Boogaert & Kouwe 1993).
Sequence of white to grey, fine- to medium-grained sandstones interbedded with siltstones and claystones, dispersed coal particles are common.

Definition of lower boundary
Conformably overlies the flood-plain fines of the Driehuis Mottled Claystone Member or the Fourteens Claystone Member.
Definition of upper boundary
Overlain by the Neomiodon Claystone Member, or it is unconformably overlain by the Helm Member or Vlieland Sandstone Formation.
Restricted to those parts of the Broad Fourteens Basin where Late Kimmerian truncation is limited (P03-Q01-K18-K15).
Locally, this member may be a lateral equivalent of part of the Neomiodon Claystone Member.
