The Shkoder-Peja Fault System (SPFS) in northern Albania forms the limit between the oblique collisional Dinarides orogen to the north and the subduction-controlled Hellenides orogen to the south. The SPFS has been associated with the northern limit of clockwise rotation of the Hellenides due to slab rollback, marks a 30º change in strike of the orogen, and has also been associated with a possible tear in the subducting Adriatic slab. To the south of the SPFS, the internal zone of the northern Hellenides is characterized by orogen-perpendicular extension, which has marked the topography and has been argued to control rapid exhumation since the late Miocene-Pliocene. In addition, the SPFS should also accommodate orogen-parallel extension and hosts some of the highest massifs of the Dinaride-Hellenide orogen in its footwall. First-order questions concerning both the dynamics and the kinematics of the Dinaride-Hellenide Transition (DHT) at the SPFS remain unanswered, including: (1) the role of the SPFS in accommodating differential motion between the Dinarides and Hellenides; (2) the temporal and kinematic relationships between range-perpendicular and range-parallel extension; (3) the onset age of the most recent phase of extension in the northern Hellenides; (4) the link between extension and exhumation; and (5) the imprint of extensional tectonics on topography and drainage patterns. This project will address these outstanding research questions by: (1) collecting new low-temperature AHe and potentially 4He/3He thermochronology data from strategic locations throughout the DHT to map out spatial / temporal patterns of exhumation and their relationship with extension; (2) integrating new and existing thermochronology data into thermo-kinematic models in order to quantitatively infer fault-motion history from the pattern of thermochronological dates; (3) establishing quantitative relationship between landscape morphology and catchment-average erosion rates from cosmogenic-nuclide data in catchments across major extensional faults; and (4) performing quantitative landscape analysis to constrain timing and rates of rock-uplift and drainage reorganization in response to extensional faulting. The overarching objective is to provide a well-constrained history of uplift, exhumation and extensional faulting associated with the DHT since the Late Miocene.
