Storage potentials - Depth maps of the German North Sea

The maps show the depths of 18 interpreted horizons from the base of the stratigraphically oldest Upper Rotliegend to the Middle Miocene unconformity. These representations are based on the evaluation of 10 deep boreholes and a close-meshed 2D seismic network. In addition to the reinterpretation of stratigraphic horizons already mapped in the Geotectonic Atlas of Northwest Germany and the German North Sea Sector (GTA) (Baldschuhn et al. 2001), further horizons were interpreted in particular in the Triassic sequence and in the Upper Rotliegend. The depth of each horizon is indicated by colour graded classes and depth contours. In addition to the depth of the respective horizons, the maps also show the distribution boundaries of the mapped formations (mostly caused by erosion, faulting and outcropping diapirs) and salt structures adjacent to the study area.
