Schematic sections across the present-day nappe stack and the former distal margin showing the main inherited structures and their role during reactivation (D1 stage). a Present-day constructed sections across the Bardella-Fuorcla Cotschna and Falotta-Tigias area (for more detail see Figs. 4 and 6). b Present-day Alpine section across the Upper Penninic and Austroalpine nappes, for loction see Fig. 3a.; modified after Mohn et al. 2011. c Architecture of the Adriatic margin based on the restoration of the Austroalpine nappe system, whith the location of futur D1 first, second and third order thrust. d Architecture of the Adriatic margin based on the restoration of the Austroalpine nappe system. e Restoration of the present-day geological sections discussed in this paper (for more detail see Figs. 5 and 7). Note the hierarchy of D1 thrust systems and the role of the inherited rift structures, in particular of the detachment systems during reactivation (for a more detailed discussion see text)
