The southern Albania thrust belt comprises Mesozoic - Eocene carbonate sequences incorporated into three major Tertiary thrust sheets verging towards the Apulia foreland in the southwest. The problem of the structural evolution has been previously approached through a hypothesis of orthogonal thin-skinned thrusting controlled by a differential areal extent ofPermo-Triassic evaporites. This thesis uses the interpretation of several seismic profiles to address questions such as those relating to the subsurface geometric patterns ofthe thrust sheets, the kinematic framework the evaporites operated in, the role ofthe pre-existing faults and the timing ofthe evolution. The interpretation demonstrates that significant along - strike changes characterize the subsurface geometry of the thrust sheets. The Permo-Triassic evaporites facilitated their buttressing against a buffer zope in the Apulian foreland primarily within an orthogonal compression regime. Regional clockwise rotation about a pivot point to the north may have provided a transpressional component along the thrusts. Pre-existing normal faults played a significant role on thrusting and accomodation of the strain partitioning. The main structural events included thin-skinned thrusting during Oligocene - Aquitaniane, formation of a buffer zone in the forelarni during Burdigalian and subsequent thrust - buttressing during the Miocene. Post - Pliocene deformation occurs in the foredeep basin.
