Quantitative reconstruction of the temporal evolution of stress in the Dutch basins

在整个地质时期不断变化的应力场与中欧盆地的一系列过程有关：例如断层的产生和复活、沉积模式的变化、流体的滞留和渗漏。根据三维断层模式和塑性重建，我们建议在一些地区进行应力反演分析。我们的研究是基于Nederlandse Aardolie Maatschappij的三维地震数据库，选择感兴趣的时间的应力场是均匀的域。我们将集中在四个关键的时间段：M。第三级和U.白垩纪/湖第三纪，侏罗纪，和三叠纪的本茨桑斯坦。将选择这些时间段的活动断层，并对其三维断层运动学进行分析。断层形态学和运动学将用于确定区域应力，使用Angelier方法（1990年）。通过对这些数据的比较，可以重建CEB沉积过程中的主要远场应力。我们的成果将提供：（1）改进了研究区盐构造的动力学演化模式;（2）加深了对盐构造反转过程以及盐构造与区域应力场相互作用的认识。

Changing stress fields through geological time were related to a wide range of processes in the Central European Basin (CEB): generation and reactivation of faults, changing patterns of sedimentation, retention and leakage of fluids for example. Based on 3D fault patterns and palinspastic reconstruction, we propose to carry out stress inversion analyses for selected horizons in a numer of areas. Our study is based on Nederlandse Aardolie Maatschappij¿s 3D seismic database, selecting domains in which the stress field at the time of interest is homogeneous. We will concentrate on four key time periods: the M. Tertiary and U. Cretaceous/L. Tertiary, the Jurassic, and the Triassic Buntsandstein. Active faults from these time periods will be selected and their 3D fault kinematics will be analysed. Fault morphology and kinematics will be used to determine the regional stress using the Angelier Method (1990). Comparion of the domain data will alow the reconstruction of the major far-field stresses active during the deposition of the CEB. Our results will provide: 1) An improved model of the dynamic evolution of the CEB in the areas studied, 2) a better understanding of the processes of tectonic inversion, and the interaction of salt tectonis and regional stress fields in the CEB.
