3D-model of the deeper underground of the North German Basin

Description

The „TUNB 3D-model of the North German Basin“ provides information of the spatial distribution of base horizons, salt structures and faults in the North German Basin (On- and Offshore). The model consists of 13 important supra-regional “litho”-stratigraphic base horizons of late Paleozoic to Cenozoic formations. The base of the Late Permian „Zechstein“ forms the base of the model and the base of the Cenozoic „Rupelium“ is the youngest modeled horizon. The digital elevation model (or sea bottom offshore) acts as the top of the model. 273 salt structures were modelled using seismic data, well data and in some cases the depth maps of surrounding horizons. The salt structures are represented by a generalized modelled boundary between salt and surrounding sediment. Due to the large number of faults in the area only selected faults could be incorporated into the model. Faults that are longer than 5 km and offset at least 3 horizons are modelled. Also selected important faults are included into the model even if they don´t match these criteria. Due to its overview scale and necessary generalisations, the model is not suitable for detailed site investigations. The 3D model is the outcome of a joint project coordinated by BGR. The modelling was conducted between 2014 and 2020 by the State Geologic Survey Organisation (GSO) of Schleswig-Holstein (LLUR), Mecklenburg-Vorpommern (LUNG), Brandenburg (LBGR), Sachsen-Anhalt (LAGB) and Niedersachen (LBEG). The area of Hamburg was modelled by LLUR, that of Bremen by LBEG and that of Berlin by the State Geological Survey of Brandenburg (LBGR). The BGR was responsible for modelling the area of the Exclusive Economic Zone of the German North Sea. The authorship of the individual state models lies with the State Geological Surveys, which created them in each case. The software package GOCAD/SKUA by Emerson Paradigm was used to create the model. In this software format the model can also be downloaded. We would like to thank EMERSON E&P for providing Paradigm SKUA-GOCAD and EPOS as part of the Academic Software Program.
