Lithological description This marine unit consists of calcareous and glauconiferous, fine sand. Some layers of sandy limestone or calcareous sandstone occur (normally three). The base is formed by a pebble layer with reworked elements (fossil fragments and rock fragments) from older deposits. The stone layers are frequently associated with coarse sediment layers (with the coarse base too). Nummulites variolarius is abundantly present.
Age Middle Lutetian.
Thickness 10 to 15 m.
Area of occurrence The formation occurs in the north of East-Flanders Flanders and Brabant and in a large part of the Antwerp Province. It continually outcrops in the Dender-Zenne region and forms the subsoil of the Flemish Valley in a narrow zone between Zomergem and Dendermonde. It occurs in outliers, as the southern hills of West- and East-Flanders and adjacent s of Hainaut and Brabant.
Type locality Oosterzele – Balegem Quarry. Sheet 22/5-6, (Gavere – Oosterzele). Co-ordinates: x = 110.8, y 179.10, z = +66 m.
