More recent models of salt deformation recognize both the in-place Middle Jurassic mother salt and displaced sheets of Middle Jurassic salt that have become detached from the mother salt as shown in the figure below. The detached salt is emplaced progressively over younger sediments because of the passive response to differential loading by sediment and gravitational forces.
