Inversion tectonics in the Central European Basin and on its southern border: An approach integrating structural geology, sedimentology, and thermochronology

晚古生代至中生代中欧盆地系统在晚白垩世至第三纪期间部分反转。这些压扭性板内应力导致较老的华力西期和/或华力西期后的NW-SE至WNW-ESE走向断层系统重新活化，产生了一些主要的基底隆起（例如，哈茨、弗莱赫廷根高）以及众多伸展断层和相关沉积盆地的反转。虽然基本的地球动力学演化的理解，在许多地区缺乏详细的信息，时间和变形程度。该项目的基本目标是获得沿着两个断面的区域缩短应变的定量估计值以及反演和折返的最严格可能的时间限制。在方法上，我们将侧重于（一）热年代学和有机成熟的日期，并量化埋藏和折返的幅度，（二）运动学恢复，以约束结构和应变幅度的几何演变，和（iii）沉积物岩相学和生物地层学和沉积学定义明确的同构造沉积物的物源分析，以确定随着时间的推移不断变化的源区。该项目旨在缩小全流域建模研究与已经完成并正在SPP 1135框架内运行的单个结构详细研究之间的长度和时间尺度差距。

The Late Paleozoic to Mesozoic Central European Basin System became, in part, inverted during Late Cretaceous to Tertiary time. These compressional-transpressional intraplate stresses led to reactivation of older Variscan and/or post-Variscan NW-SE to WNW-ESE striking fault systems, producing a few major basement uplifts (e.g., Harz, Flechtingen High) and the inversion of numerous extensional faults and associated sedimentary basins. Although fundamental to the understanding of the geodynamic evolution, detailed information on timing and deformation magnitudes is lacking in many areas. The essential goals of this project are to derive ¿ along two transects ¿ quantitative estimates of the regional shortening strain and the tightest possible timing constraints for the inversion and exhumation. Methodically, we will focus on (i) thermochronology and organic maturation to date and quantify the magnitudes of burial and exhumation, (ii) kinematic restoration to constrain the geometric evolution of structures and strain magnitudes, and (iii) sediment petrography and provenance analysis of biostratigraphically and sedimentologically well-defined syntectonic sediments to identify changing source areas through time. The project aims at closing a length- and time-scale gap between the basin-wide modelling studies and detailed studies of individual structures that have been done and are currently running in the framework of SPP 1135.
