A pilot study of seismic profiles together with RWE/DEA has shown that faults offsetting the base of the Tertiary often effect the morphology of the land surface. In this proposal we will use all seismic lines accessable in the "Schwerpunktprogramm" (SPP) for the entire area of Schleswig-Holstein to map systematically faults in the uppermost 500m of the crust and project them to the land surface. The projected fault lines are incorporated in a GIS (Geoscientific Information System) and aerial photographs/fieldwork are used to see if corresponding patterns in vegetation and surface morphology can be detected. The area of Schleswig-Holstein is characterised by widespread salt diapirism with deep troughs at the flanks; however there are also deep faults that reach from well below the base of the Permian up to the surface and appear independent of halocinesis. Mapping both types of faults for the entire area of the state will show where recent/subrecent tectonism/halocinesis was active and thus give evidence on the state of the basin since the retreat of the last continental ice sheets some 20.000 years ago.

与RWE/DEA一起对地震剖面进行的一项初步研究表明，第三纪基底偏移的断层往往会影响陆地表面的形态。在本建议书中，我们将使用“Schwerpunktprogramm”（SPP）中可访问的石勒苏益格-荷尔斯泰因州整个地区的所有地震测线，系统地绘制地壳最高500米处的断层图，并将其投影到陆地表面。预测的断层线被纳入地理信息系统（地球科学信息系统）和航空照片/实地考察，看看是否可以检测到相应的植被和表面形态的模式。石勒苏益格-荷尔斯泰因地区的特点是广泛的盐底辟作用，侧翼有深槽;然而，也有深断层，从二叠纪底部以下一直延伸到地表，似乎与盐跃层作用无关。绘制该州整个地区的两种类型的断层图将显示近期/次近期构造运动/盐生运动的活跃位置，从而提供自大约20.000年前最后一个大陆冰盖退缩以来盆地状态的证据。
