f The Pre-Permian of the Northeast German Basin

The northeast German Basin is situated between the stable Precambrian shield area of the Baltic Sea/Scandinavia to the north and the Cadomian/CaledonianlVaciscan-influenced areas to the south. Three major NW-SE striking deep fault zones occur in the area, including the suspected Trans-European Fault (TEF) separating Rügen from mainland northern Germany, the Caledonian Deformation Front (CDF) which lies to the north of Rugen and the Torrnquist Zone (TZ) comprising the Sorgenfrei-Tornquist Zone in the southeast and the Teisseyre -Tornquist none in the southeast (Fig. 1). The region comprises crystalline basement of varying Precambrian altes which is covered by a thick sedimentary succession.
