GNGTS 2023 - Atti del 41° Convegno Nazionale

Session 1.1 - POSTER GNGTS 2023 slab take-off process (Biermanns et al. 2018 with references). The continuity of the Albanides along strike is interrupted by three main transversal, roughly NE-SW striking, lineaments whose role is debated: the Shkodër-Peja, Lezha and Vlora-Elbasan fault zones. Seismological, GPS and field data suggest a normal faulting along the Shkodër-Peja since the Neogene and an earlier right-lateral kinematics (Jouanne et al. 2012). The Lezha fault zone (Aliaj et al. 2000) separates Plio-Quaternary thrust and fold belts of different axial orientation: about NW-SE in the north (Dinarides trend) and about NNW-SSE to the south. Across the fault zone also a rapid change of the GPS velocity field occurs (Jouanne et al. 2012). To the south, the SW-NE-trending Vlora-Elbasan lineament (VEL) (e.g., Roure et al. 2004) roughly marks the boundary between the Ionian and the Adriatic sectors of the External Albanides.
