Basement terminology and the main décollement as used in the 2D kinematic modelling approach in this paper. The Basement Sensu stricto refers to the Crystalline Basement. The Mechanical Basement is found under the cover, detached by the main décollement. In the study area, multiple minor thrusts are known to affect the Keuper Group evaporites, forming a décollement zone. For model purpose, the main décollement has been placed at the base of the Keuper Group. The Seismic Near-Top Basement as defined from seismic interpretation, is close to the top of the Buntsandstein Group with an uncertainty of ± 125 m
