Vestiges of Cambro-Ordovician continental accretion in the Carpathian-Balkan orogen: First evidence of the ‘Cenerian event’ in the central Serbo-Macedonian Unit

In the Balkans, Serbo-Macedonian Unit (SMU), Serbia, is thrust bounded by composite Tethyan Vardar Zone and Carpatho-Balkanides. The SMU actually emerges from beneath Neoalpine Miocene–Pliocene deposits. Both provenance geodynamic position of are poorly known still debated. This paper reviews data hitherto published includes some new field interpretations. composed a Neoproterozoic–Cambrian high-grade (para- ortho-) gneiss with peraluminous magmatic arc components (560–470 Ma). in contact Neoproterozoic upper Ordovician–Carboniferous low-grade metasedimentary succession an accretionary wedge assembly represented Supragetic basement. basement became folded, sheared metamorphosed around 490–450 Ma. Paleomagnetic point to high southern latitudes peri-Gondwanan at that time, which concurs glaciomarine evidence recorded Ordovician sediments base succession. Based on survey Stalac region, we correlate pre-Mesozoic terrane exposed Strona-Ceneri zone Alps. terrane, identified as Cenerian orogen Alaskan subduction type, developed active margin Gondwana during middle times. basement, augen migmatitic gneisses arc-related bodies, this part belt or its equivalent.
