Formal (Herngreen, Smit & Wong 1991). Amended (Van Adrichem Boogaert & Kouwe 1993).

Volcaniclast-bearing detrital layers, locally intercalated in reddish-brown, green, and grey clays and siltstones of the Zurich Formation. The volcaniclasts are opaque, green, red, and brown, fine to coarse grained, predominantly angular to subangular with a greyish, tuffaceous matrix.

Unclear whether these deposits were formed contamporaneously with the Zuidwal Volcanic Dome or were formed by erosion of the volcano (Herngreen, Smit and Wong 1991).

Characterised by a conformable, sudden transition into calcareous to dolomitic, vari-coloured mudstones with rare sand and coal bed intercalations.
