Popis: This doctoral thesis presents new thermochronological and thermometric data, cross-sections, and plate reconstructions on the kinematics and age of orogen-parallel extension and arc formation, as well as studies of basin and landscape evolution at the junction of the Dinaric and Hellenic orogens. The Dinaric-Hellenic mountain belt bends some 30° where two fault systems transect the orogen: (1) the Shkoder-Peja Normal Fault system (SPNF); (2) the Shkoder Peja Transfer Zone (SPTZ) that dextrally offsets the Dinaric-Hellenic nappes by ~75 km. The SPNF is a composite structure that cuts Dinaric folds and nappe contacts. It comprises four segments that were active under ductile-brittle conditions and downthrow the West Vardar Ophiolite in the hanging wall while exhuming two domes with anchizonal-to-lower greenschist-facies metamorphism in the footwall. Peak-metamorphic temperatures of ~280°C from RSCM (Raman spectroscopy of carbonaceous matter) analysis of the mélange of the ophiolite nappe atop the Dinaric nappe stack were attained during obduction in latest Jurassic-Early Cretaceous time, followed by cooling of the ophiolithic mélange to
