“…Hence, the deeply subsided part of the Lower Saxony Basin can represent one of the en-echelon pull-apart basins formed along the SW margin of the CEBS due to transtensional deformation along the Elbe Fault System (EFS). The transtensional concept is supported by seismic data showing latest Jurassic-Early Cretaceous flower structures in other NW-SE oriented sub-basins, like those of Lower Saxony Basin (Betz et al, 1987), of the Subhercynian Basin (Otto, 2003), the SE North Sea and the West Netherlands (Nalpas et al, 1995).…”

A selection of reflection-seismic lines from the southern part of the Central European Basin System and its southern margin were used to establish the spectrum of extensional and compressional deformation structures and to calibrate the timing of these events. The lines are arranged in a N-S and an E-W transect running across the Pompeckj Block and the Lower Saxony Basin in Northern Germany. The structural record provided by the seismic data points to an interplay between far-field horizontal stresses and vertical movements of the basin floor, the latter only weakly correlated with the development of seismic-scale tectonic structures. A detailed seismo-stratigraphic analysis indicates that Late Triassic-Jurassic extension has been the principal control on the structure of the E-W profile, whereas the N-S profile is dominated by compressional structures associated with Late Cretaceous inversion. Overprint effects of extension and inversion tectonics can be classified among a few distinct tectonic events accompanied by movements of the Upper Permian salt: firstly, an episode of subsidence and diapiric rise in the Keuper; secondly, a clear Jurassic-to-Early Cretaceous extension recorded by normal faulting and differential subsidence. The latter was interrupted by a major episode of Late Jurassic uplift. Thirdly, a Late Cretaceous-Early Paleogene basin inversion was associated with approximately N-S compression; and fourthly, recurring extension during the Cenozoic associated with diapiric rise and collapse. The Mesozoic extension is expressed in a number of normal faults that were most active during the Early Cretaceous localised subsidence within the Lower Saxony Basin. The deformation associated with the Late Cretaceous inversion was partly decoupled along the salt. The compressional deformation at the southern margin of the basin was thick-skinned in style, characterized by folding and faulting of the Mesozoic sedimentary fill and pre-Zechstein strata. Further north, towards the centre of the basin, folding and reverse faulting were mostly concentrated above the salt. The tectonic evolution of the investigated area suggests the presence of a zone of crustal weakness along the SW margin of the Central European Basin System which allowed strain localization in response to a favourable oriented stress field.

“…Whereas such relatively exact timing has been achieved for the basement highs at the present-day southern margin of the Central European Basin, dating is less precise in its more central parts where the phase of inversion is generally bracketed between the Coniacian and Paleocene (Kockel 2003;Mazur et al 2005). For example, Otto (2003) places the main inversion event between Maastrichtian and Paleocene time based on seismostratigraphic interpretation of 2D seismic sections crossing the Haldensleben and Gardelegen Escarpments (directly north of Flechting High and Calvörde Block, respectively; Fig. 1).…”

The Harz Mountains and the adjacent Subhercynian Cretaceous Basin figure as the most prominent surface representative for Late Cretaceous inversion structures in Central Europe. Facies, depositional architecture and provenance of the basin fill reflect mechanisms and timing of the exhumation of the Harz. From Hauterivian to Early Santonian there is no evidence for detrital input from the nearby Harz area. Sediments are mature quartzarenites derived from Paleozoic basement rocks and/ or recycled Permian to Mesozoic sedimentary rocks. This situation changed drastically in Middle to Late Santonian when freshly exhumed and eroded Mesozoic sedimentary cover rocks of the Harz were delivered into the basin. Feldspar and lithoclasts reflect erosion of Triassic and, in places, Jurassic to Turonian strata. Apatite and garnet in heavy mineral spectra are derived from largely unweathered Lower Triassic Buntsandstein as indicated by apatite and garnet chemistry. In Early Campanian, Paleozoic lithoclasts indicate erosion cutting down into the basement of the Harz. Simultaneous strong decrease of feldspar, garnet and apatite suggest an almost complete removal of the 2-3 km thick Mesozoic cover of the Harz within only 2-4 Myr. This translates into an exhumation rate of approximately 1 mm/a consistent with apatite fission track data from granitoid rocks of the Harz Mountains.

“…Reflection seismic data (Figs. 4,5) show an uplift of the basin floor in the order of 1-2 s two way travel time (about 3-4 km) at the SW margin of the basin associated with folding and thrusting of the basin fill (Scheck et al 2002;Otto 2003;Kossow and Krawczyk 2002). Contrastingly, the basement in the central part of the basin is not uplifted and deformation is mechanically decoupled along the layer of Zechstein salt.…”
