Abstract: Development of structural styles and tectono-sedimentary evolution in the Northeast German Basin

The Northeast German Basin (NEGB) is one of a series of related intracontinental basins extending from the North Sea to Poland. Following Permo-Carboniferous magmatic activity, rapid thermal-induced subsidence occurred from Early Permian to Middle Triassic times. Subsidence was interrupted by phases of inversion-related uplift in Late Jurassic and Cenozoic times.

Despite extensive hydrocarbon exploration, details of the tectono-sedimentary evolution are still unclear largely because extensive salt movements complicate the analysis of regional tectonics. With the aid of a basinwide balanced cross section the structural development has been studied and the understanding of the tectono-sedimentary evolution has been improved.

Interpretation of the DEKORP-BASIN 9601 deep seismic reflection profile together with more than 2000 km of newly-released industrial seismics has facilitated the detailed analysis of the sedimentary succession in the northern part of the NEGB. Published data from the southern part of the basin were used to compile a basinwide geological profile across the entire basin. Stepwise restoration of this profile, in a series of time-slices beginning with the Zechstein, allowed the development of the structures at different stratigraphic levels and the role of pre-existing structures to be ascertained. Furthermore, the importance of the Zechstein salt in controlling the structural pattern and the sediment distribution was examined.
