Fig. 13

Modelled best-fit geometry of the Eo-Oligocene inversion of Mesozoic half graben systems. This figure is a zoom-in of the undeformed central part of the kinematic forward model (Fig. 6d) postdating deposition of the Middle Eocene Foraminiferal Limestone and formation of the High Karst internal nappe stack. The black lines represent normal faults generated during the Middle Triassic (a), (LTS) and Uppermost Jurassic (b), (PTS). The red faults show the modelled geometry of the generated backthrusts. The numbering of faults corresponds to the relative time of initiation of the faults. The blind duplex is marked by the letter 'a' and backthrusts are marked by the letter 'b'. a The reactivation of the LFS. Here the backthrusts 4 (Jadovno Fault) and 5 (Bužim Fault) by-passed the hanging wall of the two deep Middle Triassic normal faults, partly the normal fault geometry is reactivated. Backthrust 3 (Brušane-Oštarije Fault) is not related to a previous normal fault, since no Middle Triassic was deposited within the hanging wall (Fig. 3a). b The inversion of the Plitvice Fault System. Here the best-fit geometry suggests that the normal faulting occurred during upper Jurassic and that the half grabens were inverted during the Cenozoic contraction mainly by hanging wall by-passes
