|Definition||In the eastern part of the Netherlands this formation consists of two distinct sandstone units with an intercalated layer of reddish-brown siltstone or silty claystone. Only the equivalent of the lowermost bed is probably present in the western Netherlands offshore. The member is developed as a massive, light-coloured, arkosic sandstone in the western Netherlands offshore and the southern onshore. The high quartz content and quartz cementation of the sandstones is typical there. In the northern offshore, halite cementation occurs in the vicinity of Zechstein salt domes.|
