Strain partitioning in a large intracontinental strike-slip system accommodating backarc-convex orocline formation: The Circum-Moesian Fault System of the Carpatho-Balkanides

The evolution of oroclines is often driven by the interplay subduction and indentation associated with complex patterns deformation transfer from shortening to strike-slip extension. We study kinematics mechanics in an orocline a backarc-convex geometry, European Carpatho-Balkanides Mountains. Within this orocline, kinematic Serbian Carpathians segment less understood. results demonstrate that overall was accommodated Circum-Moesian Fault System surrounding Moesian indenter, where strain partitioned network coeval strike-slip, thrust normal faults. This system represents one largest intracontinental zones, northward-increasing accumulated 140 km dextral offset along previously known newly found These faults significant part their eastwards thrusting Balkanides westwards orogen-parallel extension formation intramontane basins. correlation paleogeographic geodynamic reconstructions demonstrates fault Carpathian embayment, resulting laterally variable amounts translation rotation Platform. onset slab retreat backarc at 20 Ma has dramatically increased rates ~3.5 mm/yr ~2 cm/yr, facilitated pull exerted retreating slab. Our requires partitioning analysis adapted specificity is, therefore, able quantify observed patterns.
