Fig. 9 

Part 1 of the 2D kinematic forward model from the Geneva Basin to the Bienne Valley (deformation steps 0 to 5). In the individual deformation steps, the active thrust is shown in black and inactive thrusts are coloured in red. The numbering of the faults corresponds to the sequence of deformation. Step 0 corresponds to the Northern Alpine Foreland stage prior to the Jura thrusting and represents the initial layer cake model supplemented by the information about the basement depth (Fig. 8). Step 1 indicates the first deformation and step 11, the last one. The Mesozoic cover shown in the forward model, has been built on the Near-Top Basement line (Fig. 8). The 1st and 2nd deformation steps the folding of the Crêt de la Neige Anticline related to the movement along the Reculet Thrust. The steps 3 to 5 show the movement along the Crêt Chalam Thrust with its imbrication, leading to the Bellecombe Anticline. The algorithm used in Movetm version 2020.1 with the resulting shortening is detailed for each step
