Definition Sandstone-dominated succession, similar to Lower Slochteren Member, but less conglomeratic NAM and RGD (1980) .
Upper Boundary The unit is overlain either by the red-brown claystones of the Ten Boer Member of the Silverpit Formation or by the black bituminous shales of the Coppershale Member of the Z 1 (Werra) Formation.
Lower Boundary The member usually overlies the Ameland Member of the Silverpit Formation. In the Terschelling-Ameland area it conformably rests on the Buren Member of the Silverpit Formation, recognisable by the absence of the Lower Slochteren Member.
Correlation The Upper Slochteren Member becomes part of the main Slochteren Formation on the flanks of the basin, whereas it grades laterally into the main Silverpit Formation towards the basin centre. The Ameland and Ten Boer Members of that formation are partially its lateral equivalents.
Distribution The member is restricted to the transitional area between the basin and the fringes of the basin of the Southern Permian Basin. The Upper Slochteren Member has a smaller areal distribution than the Lower Slochteren Member. In the area of Ameland and Terschelling, however, the member occurs without associated Lower Slochteren Member.
