|Definition||A thick sequence of light to dark-grey, dark- to yellowish-brown and brownish-black, and light yellowish-brown to dusty yellow-brown limestones. The dense limestones are micritic, biosparitic to biomicritic, locally oolitic and abundantly fossiliferous. In places 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.|
|Age||Middle to late Visean (V2 to V3a; late Arundian to Holkerian), locally even early Visean (V1) in the lower part of the member. The member yielded the diagnostic foraminifers Palaeotextularia, Eotextularia diversa, Eoparastaphella, Dainella, Bessiella, Pseudolituotubella, Archeodiscus (Glomodiscus) and Loeblichia, and the calcareous algae Girvanella densa and Koninckopora.|
