Structural characterization and dating of an active strike-slip fault that passes from bedrock into unconsolidated sediments

拟议的项目有两个主要方面。一个是分析从基岩进入松散沉积物的断层，以及断层带几何形状和内部断层结构的相关影响。第二个方面是有系统地发展a）基于GPR的不同主体材料中的断层可视化，和B）使用发光方法改进直接断层定年技术。该项目将利用沙箱模拟模型，将允许分析从基岩到盆地填充物的松散沉积物的过渡。该研究将为断裂带结构的横向变化和扇断层的形成提供新的认识。这对于生成整体断层模型和更好地理解断层发育和相关的地震危险性是至关重要的。

The proposed project has two main aspects. One is to analyse a fault that passes from bedrock into unconsolidated sediments, and the related effects of fault zone geometry and internal fault structure. The second aspect is the methodical development for a) the visualisation of faults in different host materials based on GPR, and b) to improve direct fault-dating techniques using the luminescence approach. The project will utilise sandbox analogue models that will allow to analyse the transition from the bedrock into the unconsolidated sediments of the basin-fill. The study will deliver new insights into the lateral changes of the structure of a fault zone and the formation of splay faults. This is crucial for the generation of a holistic fault model and for a better understanding of fault development and the related seismic hazard potential.
