In this study, we combined low-t thermochronology with outcrop- to micro-scale kinematic and petrological observations in the metamorphic basement of the Juhor Mts. in Central Serbia. The Juhor Mts. comprise northern parts of the Europe-derived Serbo–Macedonian Unit, at the transition towards the Adria-derived tectonic units of the Internal Dinarid...

The Berane Basin is a Miocene, northeast-southwest oriented in-tramountain basin of the Dinarides, overlying the pre-neotectonic basement of the Drina-Ivanjica unit, the East Bosnian-Durmitor unit and the Western Vardar Zone. The structural evolution and the tectonic regimes that controlled the formation of the Berane Basin are not fully understood...

Asthenospheric flow is a major driver of plate motions and lithosphere deformation. Previous studies have modelled the asthenospheric flow linked to the negative buoyancy of subducting slabs. However, orogenic systems associated with slab retreat are characterised by a more complex asthenospheric flow related to larger-scale processes including oro...

Volcano-sedimentary basins located in the orogenic hinterland area overlying subducted slabs are observed worldwide to be driven by the switching tectonic regimes induced by the changing mechanics of the slab. Despite many qualitative studies, the quantitative link between the subducted slab?s mechanics and the overlying basins? evolution is less u...

The Cretaceous sedimentation along the NE Dinarides margin occurred in basins above the Europe-dipping Neotethyan Sava subduction zone positioned between Adria- and Europe-derived continental units. The Cretaceous sedimentation on the upper plate of the Sava subduction system took place in a fore-arc basin, developed in frontal parts of the active...

A microtectonic study was conducted in the Levac region of central Serbia. Here, the tectonic contacts between the Europe?derived units, including the Serbo-Macedonian unit and Jurassic sedimentary cover of the European margin, and the Eastern Vardar Ophiolitic unit, are exposed at the surface. The results indicate that the contact zone underwent a...

The Fruška Gora in north-western Serbia exposes the northernmost surface occurrences of ophiolites that derive from the obduction of the Vardar Ocean over the Adriatic continental margin. The late Oxfordian – early Kimmeridgian to late Kimmeridgian – early Tithonian radiolarians were determined from the blocks of radiolarites that constitute part o...

One key element in the current debate analysing the Central Mediterranean evolution is the Cretaceous structure and kinematics of the present‐day oroclinal bent contact between Adria‐ and Europe‐ derived continental units in the Dinarides, interpreted in different tectonic reconstructions as a subduction‐related thrust system or a large‐scale strik...

Continental indentation is associated with deformation transfer from shortening to strike-slip faulting and is often affected by subduction related processes such as slab roll-back driven back-arc extension. We use crustal-scale analogue modelling to investigate the effects of extension direction on the strain partitioning and deformation transfer...

The evolution of oroclines is often driven by the interplay of subduction and indentation associated with complex patterns of deformation transfer from shortening to strike-slip and extension. We study the kinematics and mechanics of indentation in an orocline with a backarc-convex geometry, the European Carpatho-Balkanides Mountains. Within this o...

This paper presents the first Upper Cretaceous remains of fish in Serbia, discovered near the village of Struganik. This is also the first described find of Mesozoic fish in Serbia. A stone slab with visible contours of an almost complete fish, with a total body length of about 20 cm, was excavated from the Struganik quarry. Most bones are preserve...

The Vršac Mts. in NE Serbia represent the key area to investigate structural relations between the Northern Serbo-Macedonian Subunit and Supragetic Unit of the Dacia Mega-Unit. The geodynamic events during the Variscan orogeny in the Late Paleozoic colligated the two units and led to their metamorphic differentiation. The Late Cretaceous extension...

Large-scale strike-slip faults are associated with significant strain partitioning in releasing/restraining bends and often display map-view curvatures ending in horse-tail geometries. Such faults are commonly associated with indentation tectonics, where shortening in front of indenters is transferred laterally to transpression, strike-slip and the...

Particle Image Velocimetry (PIV), a method based on image cross-correlation, is widely used for obtaining velocity fields from time series of images of deforming objects. Rather than instantaneous velocities, we are interested in reconstructing cumulative deformation, and use PIV-derived incremental displacements for this purpose. Our focus is on a...

Abstract: High-resolution biostratigraphic dating of (hemi)pelagic limestones stratigraphically adjacent to syn-depositional bimodal magmatites in central Serbia, based on planktonic foraminiferal assemblages, determines that the magmatism occurred during Coniacian to Santonian. This bimodal magmatism, which includes both basaltic magmas with assoc...

Highly curved orogens often demonstrate a complex poly-phase tectonic evolution and significant strain partitioning. While the oroclinal bending towards the outer arc is understood to be often driven by rapid slab roll-back, processes driving such bending towards the back-arc domain are less understood. The Serbian segment of the larger, highly ben...

Vardar mega-unit represents complex tectonic unit, which was structured during Mesozoic tectono-depositional evolution of Neotethys and the adjoining continental margins. Vardar mega-unit can be subdivided into the three tectonic entities characterized by contrasting lithostratigraphic and structural features. Going from west towards east these are...

Fault-related folds and hanging-wall structures reflect the geometry of the main thrusts in foldthrust belts. The results of the structural analysis of the Supragetic Unit metamorphic basement in eastern Serbia at map-, outcrop- and thin-section scale, and its importance for the late Early Cretaceous nappe-stacking are presented in this paper. The...

The tectonic evolution of the Carpatho-Balkanides Mountains is less understood in the critical segment of the Serbian Carpathians due to lack of available kinematic data. We have performed a field kinematic analysis combined with existing information from previous local and regional studies by focusing on the internal part of this orogenic segment,...
