ABSTRACT

We aim to describe flow patterns that develop in the mechanically stratified evaporite sequence during the basement-involved deformation. We use numerical methods and examine various initial setups, where different lithological profiles of the sequence and vertical offsets along the fault are tested. To better illustrate the impact of layering, we compare our results with the models containing no internal stratification. The results clearly show that the mechanical stratification can have a great impact on the flow pattern initiating heterogeneous deformation within the sequence.
