Major target of the interdisciplinary project is the compilation and interpretation of a series of high-resolution maps to study the structural evoltuon of the coastal area of the Mecklenburg Bay (northern Germany) with geophysical and geologcial data in order to identify and evaluate potential fault systems in different scales. The pre-Alpine to Recent evolution of the Central European Basin System, which is presently a low-seismic area, will be investigated. The understandig of the post- and pre-Alpine structural history and the reactivation of faults requires the characterizsation of deformation including mapping of faults, fault kinematics and slip/subsidence rates over variois geological time scales. A unique commercial data base of the former GDR provides some 1770 km of seimic profiling across major faults, covering the sedimentary sequences from the Rotliegend on. But, seismic information needs to be reprocessed and interpreted in terms of analyzing the interplay between the possible causative processes, like change of the regional stress field, reactivation of Paleozoic tectonic lineaments, halokinesis, and recent processes like sedimentation and glaciation, and their impact on interaction fault and sedimentation.

该跨学科项目的主要目标是编制和解释一系列高分辨率地图，利用地球物理和地质学数据研究(德国北部)梅克伦堡湾沿岸地区的构造演化，以查明和评价不同规模的潜在断层系统。将研究中欧盆地系统在阿尔卑斯山前到最近的演化，目前中欧盆地系统是一个低地震地区。为了了解阿尔卑斯山后和前阿尔卑斯山构造历史，以及断裂的重新活动，需要了解形变的特征，包括不同地质时间尺度上的断层填图、断层运动学和滑动/沉降速率。前德意志民主共和国独特的商业数据库提供了跨越主要断层的约1770公里的地震剖面，涵盖了自旋转式断裂带以来的沉积序列。但是，地震信息需要重新处理和解释，以分析可能的成因过程之间的相互作用，如区域应力场的变化，古生代构造线形的重新激活，晕动作用，以及现代过程如沉积和冰川作用，以及它们对相互作用断层和沉积的影响。
