Modelled units

The DGM-deep v5.0 model comprises the geometrically coherent succession of 12 seismic interpreted horizons and one thickness-based horizon, which were modeled at 250x250m grid resolution. The seismically interpreted horizons represent the (near) bases of the following lithostratigraphic units and include the Limburg Group (DC, Late Carboniferous), Zechstein Group (ZE, late Permian), the Lower and Upper Germanic Trias groups (RB+RN) , the Altena Group (AT, Early and Middle Jurassic), the Schieland and Niedersachsen groups (S, Late Jurassic-Early Cretaceous, ), the Rijnland Group (KN, Early Cretaceous), the Chalk Group (CK, Late Cretaceous- Early Paleogene), the Lower and Middle North Sea groups (N, Paleogene) and the Upper North Sea Group (NU, Neogene). Two horizons have been interpreted at respectively subgroup and formation level; i.e. the Caumer Subgroup (DCC) and the Posidonia Shale Formation (ATPO; Toarcian near base Middle Jurassic). The base of the Upper Rotliegend Group (RO, Permian) is constructed by adding a thickness grid based on well data to the depth of the base Zechstein Group.
