Deep reaching fluid-flow in the Central European Basin System

三个世纪以来，在中欧盆地系统的不同地区收集了大量咸水上升的证据。这些盐泉是暂时的，在空间上不稳定(流浪)。最终的原因尚不清楚，然而，水的化学成分表明了深层(前第三纪)的起源。上升相对稠密的咸水需要作用力，既可以是盆地内部的力，如热力变化，也可以是外部力(水力压头)。由于地形相当平坦，改变水头的局部效应是不可行的，而初步模型方法表明，与温度场有足够强的相互作用，以诱导自由对流。将结合水文学、水化学和模型研究这一过程的动力学。该提案将以中欧盆地系统为例，通过评估盆地充填体内最有可能的现今流动状态、与热场以及断层系统和盐结构的相互作用，直接促进不同应力条件下沉积系统的SPP动力学的“现代状态和年轻过程”这一主题。此外，拟议的工作将需要并提供以“流体和盐动力学”为主题的反馈，而且就考虑到深层热场而言，还将与“地壳的结构和演化”这一主题有一些联系。最终目标是了解盆地内在的流体动力学以及可能的外力的影响，如盆地南缘的水头冲击。

Extensive evidence for rising saline waters has been gathered through three centuries and in different regions of the Central European Basin System. These saline springs are temporary and spatially instable (vagabonding). The ultimate causes are not yet clear, however, the chemistry of the waters indicates a deep (Pre-Tertiary) origin. Rising relatively dense salty waters requires forces, either intrinsic to the basins like thermal variations or external (hydraulic head). Because the topography is rather flat, local effects from a varying hydraulic head are not feasible while preliminary model approaches indicate a sufficiently strong interaction with the temperature field in order to induce free convection. The dynamics of the process will be studied in combining hydrology, water chemistry and modelling. The proposal will directly contribute to the theme "recent state and young processes" of the SPP Dynamics of Sedimentary Systems under Varying Stress Conditions by Example of the Central European Basin-System by evaluating the most likely present day flow regime within the basin fill, its interaction with the thermal field as well as fault systems and salt structures. In addition, the proposed work will need and provide feed back with the theme "Fluid- and salt-dynamics" and will also have some connection to the theme "structure and evolution of the crust" as far as the deep thermal field is considered. The final objective is, to understand the fluid dynamics intrinsic to the basin as well as the effects of possible external forces like the impact of the hydraulic head at the southern margin of the basin.
