“…Geophysical experiments primarily targeted the entire basin or entire crust, e.g., in the frame of the EGT (EUGENO-S Working Group 1988; Thybo 1990, Aichroth et al 1992, BABEL (BA-BEL Working Group 1993), MonaLisa (Abramowitz and Thybo 1998), DEKORP Basin'96 and related offshore research (Meissner and Krawczyk 1999;Krawczyk et al 2002), and, POLONAISE'97 (Guterch et al 1999), TOR (e.g., Gossler et al 1999;Hossein Shomali et al 2002).…”

The recent evolution of the north German Basin (NGB), which is presently a low-seismic area, was partly affected by glacial loading and unloading of the ice masses. Major stresses acting within the NGB are induced by the North-Atlantic ridge push, the ongoing Alpine collision, and the post-glacial rebound of Fennoscandia. Present-day horizontal stresses within the NGB are directed generally NW-SE, but fan and bend north of 52°N towards NNE. Major basement faults are directed NW-SE, minor faults NE-SW and NNE-SSW, and are clearly detectable in geomorphological and satellite lineaments. Furthermore, the drainage pattern and the distribution of lakes in northern Germany follow exactly block boundaries and, hence, mark zones of present-day subsidence. The understanding of the post-glacial morphology and reactivation of faults requires a view into the very heterogeneous crust and upper mantle below the NGB. The re-adjustment of the individual fault blocks during postglacial relaxation of the lithosphere leads to differential, crust-dependent uplift and, probably, to the formation of Urstrom valleys. The Urstrom valleys and terminal moraines in northern Germany appear to parallel the major tectonic lineaments and lithospheric ''block'' boundaries. The lithospheric memory is expressed in the post-glacial landscape evolution of the NGB.

“…In Northern Germany, a high-velocity middle crust and lower crust to the north terminates abruptly at the Elbe Line (Aichroth et al, 1992;Thybo, 2001). In the MONA LISA lines, the termination of Baltica in the lower crust appears as a transition from high (>7.0 km s À1 ) velocities in Baltica crust to low velocities (<6.4 km s À1 ) in the 'pure' Avalonian portion of the crust (Abramovitz and Thybo, 2000;Abramovitz et al, 1998). Thus, a possible interpretation is that highly extended Baltican lithosphere extends as far west as 60-80 km at the P4 profile.…”

“…1). A number of deep seismic surveys were carried out in the past to investigate the crustal and mantle structure throughout the CEBS (e.g., Trappe 1989;Reichert 1993;Abramovitz et al 1998;DEKORP-BASIN Research Group 1999;Maystrenko et al 2003). Thereby, the area of the Glückstadt Graben is of special interest in order to reveal the deep crustal structures along the transition zone from the Precambrian Fenno-Scandian Shield to the Caledonian crust in NW Germany.…”

The influence of deep crustal processes on basin formation and evolution and its relation to current morphology is not well understood yet. A key feature to unravel these issues is a detailed seismic image of the crust. A part of the data recorded by the hydrocarbon industry in the late 1970s and 1980s in the North German Basin were released to the public recently. The seismic reflection data were recorded down to 15 s two-way travel time. The mean Common Midpoint fold of about 20 is relatively low compared to contemporary seismic acquisitions. The processing of the 1980s focussed on the sedimentary structures to explore the hydrocarbon potential of this area. We applied the Common Reflection Surface stack technique to the data sets, which is well suited for low-fold data. The reprocessing was focussed on the imaging of the subsedimentary crustal range. The reprocessed images show enhanced reflections, especially in the mid and lower crustal part. Also, the image of the salt structures in the graben area was improved. Furthermore, the reprocessed images indicate an almost flat Moho topography in the area of the Glückstadt Graben and an additional lower crustal structure, which can be correlated with a high-density body found in recent gravity modeling studies.
