U-Pb geochronology of zircon grains retrieved from magmatic rocks intruding the Jadar block terrane in the central Balkans is used here to add new constraints on the terrane accretion processes and the provenance of crustal sources of this potentially exotic crustal block. Using an unorthodox approach, we analyzed zircons extracted from the product...

Extension across the southern Pannonian Basin and the internal Dinarides is characterized by Oligo‐Miocene metamorphic core complexes (MCCs) exhumed along mylonitic low‐angle extensional shear zones. Cer MCC at the transition between Dinarides and Pannonian Basin occupies a structural position within the distal‐most Adriatic thrust sheet and origin...

Structures at Cer MCC in western central Serbia reveal evidence for Top-N transport during exhumation. Exhumation was active until at least 17 Ma, according to Ar-Ar geochronology an most likely related to reactivation of Maastrichtian suturing thrusts of the Sava Zone as low-angle detachments. Magmatism might be related to upwelling of Adriatic as...

The Mirdita massif is part of the West Vardar Ophiolite Unit which itself crops out along the entire Balkan-Peninsula (Fig.1). The inversion of the Neo-Tethan ocean occured during Bathonian to Callovian by intraoceanic subduction. This led to the formation of a metamorphic sole with HT-assemblages along the plate interface by overthrusting fluid-ri...

Ar/Ar-in-situ geochronology provides a powerful tool to study the inter-and intra-granular age variations of minerals while maintaining textural control of the sample. In order to date exhumation/extensional deformation in the Internal Dinarides, we selected samples from two metamorphic core complexes located at the distal Adriatic passive margin a...

The obduction of ophiolites formed at mid-oceanic ridges onto passive margins is preceded by intraoceanic subduction. During incipient subduction, metamorphic soles with HT- assemblages form along the plate interface by overthrusting fluid-rich lower-plate material with hot, dry ultramafics of the upper plate. As lower plate material undergoes prog...

The Sava Zone represents a suturing accretionary prism separating the northernmost Adria-derived thrust sheets of the Dinarides in a lower plate position from Europe-derived units in the hanging wall. It hosts a Late Cretaceous succession consisting of predominant trench fill sediments and subordinate bimodal igneous rocks. Both Sava Zone and north...
