|Abstract:||Epirus, in NW Greece, comprises a sequence of Tertiary thrusts and represents the destroyed eastern passive margin of the Apulian platform. A large number of both west-vergent thrusts and east-vergent back-thrusts occur in the area. E-W trending strike-slip fault zones play an important role in the Alpide evolution by dissecting the N-S trending orogene. The study of two heavily deformed areas, both located along the Souli strike-slip Fault System, have been performed and it is here presented. Detailed mapping and tectonic analysis of the structures have been carried out in both examples. Geological cross-section have been prepared and, taking into account a ramp-flat model of contractional deformation, it has been possible to interpret these sections down to a hypothetical basal detachment and consequently to attempt the palinspastic reconstruction of the involved tectonic units. The mesostructural analysis carried out in the area also permits to describe the kinematics of the main tectonic units. In the light of the presented geological and structural data the quantifiable amount of sortening is much larger than know in the literature and, for the Ionian Zone of Epirus, it is proposed a shortening greater than 50%.|
