Definition The formation consists of a basal, grey sandstone and overlying red claystone unit. In the Off Holland Low, the formation locally contains an unnamed sandstone interval intercalated in the claystones.
Upper Boundary The upper boundary is picked at the base of the Röt Evaporite Member. In the basin-fringe area, in the absence of the Röt Evaporite, this boundary may be difficult to identify.
Lower Boundary The Solling Formation unconformably overlies the Main BuntsandsteinSubgroup, or in areas of severe pre-Solling erosion, the Lower Buntsandstein Formation. The unconformity is usually marked by a well-cemented, basal sandstone, which shows a more pronounced response on wireline logs than the sandstones of the underlying Main Buntsandstein Subgroup.
Distribution The formation can be recognised across the entire distribution area of the Upper Germanic Trias Group.
Age Latest Scythian. Samples from Germany revealed a latest Scythian age according to Brugman (1986) and van der Zwan and Spaak (1992) report a similar age.
Depositional Setting The sandstones in the formation are braided-river deposits, whereas the claystones were deposited in a lacustrine setting.
