“…The Vardar megasuture zone arose at the expense of N-S-directed (in Mesozoic reference) convergence between the Apulia/Adria microplate and the former Eurasian margin (locally, Eurasian margin is represented by the Serbo-Macedonian Unit and Tisza microplate). The pre-convergence highly complex Neotethyan paleogeography (e.g., MENANT et al, 2016;ArGNANi, 2018;SPAhić et al, 2020) is best illustrated by a conceptual debate revolving around the Mediterranean geodynamics: one ophioliteone ocean (e.g., CSoNToS & VöröS, 2004;SChMiD et al, 2008;BorToLoTTi et al, 2013) vs. two ophiolitesone ocean model (roBErTSoN et al, 1996;DiMiTriJEVić, 2001;STAMPFLi & koZUr, 2006). Similarly, the complex Neotethyan plate motions towards the intervening EVZ and Serbo-Macedonian Unit including the interaction of the West Vardar ophiolites and Drina-ivanjica block remain to be another topic of discussions.…”

A composite paleogeographic and plate kinematic spatiotemporal reconstruction of the exhumed Neotethyan cross-lithospheric footwall amalgamation (Jastrebac dome) incorporates the two formerly underplating oceanic entities, West Vardar-and East Vardar Zone. These ophiolite-bearing agglomerations are unroofed within the accretionary Paleogene to Miocene core-complex, beneath the Serbo-Macedonian overriding plate. The exposed Neotethyan crustal amalgamation is comprised of: an (i) folded trench assemblage of uncertain Mesozoic? Paleogeographic affinity metamorphosed under a greenschist-grade (West-vs. East Vardar Zone or Neotethyan crust-vs. its back-arc system?) sandwiched beneath the overlying (ii) late Cretaceous-Paleogene (meta)turbidites. To make matters more intricate, at the closest proximity of the dome (Mali Jastrebac Mountain) there is a similar (iii) greenschist-facies amalgamation comprised of the Neoproterozoic-Lower Paleozoic ocean-floor assembly (Supragetic basement). The interpretations of this rather controversial cross-lithospheric structure include a reassessment of the obduction sequence, and are underpinned by the restoration of the near-trench microplate motions. The study addresses the (1) local finite configuration (Serbo-Macedonian hanging wall vs. Neotethyan intraoceanic arc) and the (2) spatiotemporal geometry of the principal (micro)plate boundaries (Serbo-Macedonian Unit vs. Apulia/Adria). Unlike the earlier proposal of the ophiolite obduction onto the Serbo-Macedonian Unit onto the Apulia/Adria hinterland (or external segment of the "Dacia mega-terrane"), we here propose a west-vergent obduction of the East Vardar Zone ophiolites onto the descending Neotethyan lithosphere (West Vardar ophiolites)-a similar scenario to its continuation in Greece (Peonias subzone).
