“…f Interpolated P-wave velocity of the uppermost basement from seismic refraction profiles; the dotted line ellipse shows the area of anomalous velocity (anisotropy) discussed in the text. The data in the map c are from modern seismic refraction experiments/profiles: POLONAISE'97: Guterch et al (1999); profile P1-Jansen et al boreholes by Stefaniuk and Klityński (2007). A proper mask for this map is calculated as having value 1 where data are available and value 0 elsewhere.…”

A dense grid of multichannel high-resolution seismic sections from the Bay of Kiel in the western Baltic Sea has been interpreted in order to reveal the Mesozoic and Cenozoic geological evolution of the northern part of the North German Basin. The overall geological evolution of the study area can be separated into four distinct periods. During the Triassic and the Early Jurassic, E-W extension and the deposition of clastic sediments initiated the movement of the underlying Zechstein evaporites. The deposition ceased during the Middle Jurassic, when the entire area was uplifted as a result of the Mid North Sea Doming. The uplift resulted in a pronounced erosion of Upper Triassic and Lower Jurassic strata. This event is marked by a clear angular unconformity on all the seismic sections. The region remained an area of non-deposition until the end of the Early Cretaceous, when the sedimentation resumed in the area. Throughout the Late Cretaceous the sedimentation took place under tectonic quiescence. Reactivated salt movement is observed at the Cretaceous Cenozoic transition as a result of the change from an extensional to compressional regional stress field. The vertical salt movement influenced the Cenozoic sedimentation and resulted in thinskinned faulting.

“…Because of the thickness of Mesozoic and Cenozoic sedimentary cover rocks, this has proved difficult and controversial, and depends largely on the results of seismic profiling. Both the Polonaise P1 and TTZ profiles (Jensen et al 1999;Grad et al 1999) show a clear change of mid-crustal structure north of the Moldanubian Thrust, suggesting that it continues northward as a major feature termed the Moravian Line by Winchester et al (2002). In the TTZ profile the mid-crustal break illustrated is displaced eastwards compared to Polonaise PI: this may suggest dextral displacement of the Moravian Line by strike-slip faulting between the two profiles, perhaps along the Dolsk Line (Grad et al 2002).…”
