Status
Formal (Van Adrichem Boogaert & Kouwe 1994).
Lithological description
Thick sequence of light to dark-grey, brownish-black, light-yellow to dark-brown limestones. The dense limestones are micritic, biosparitic to biomicritic, locally oolitic and abundantly fossiliferous. In places with coarsely crystalline calcite veins occur. Intergranular bituminous, organic material is often present. Locally, the limestones are dolomitized, especially near fault zones, or silicified in the leached zone in areas where later erosion truncated the Zeeland Formation.
