Figure 22-Reconstruction (in sequence [animation]) of cross section in Figure 21. The restored base of the Vicksburg section remained subhorizontal through time. Slices of Eocene shales (dull green) were stripped off the footwall and carried eastward along the detachment. This sliding system does not directly involve salt withdrawal. Reconstruction is by the MESH method. Vx D, C, B, A indicate four successive Vicksburg levels (oldest to youngest).
