Extensional unroofing of the Veliki Jastrebac dome (Serbia)

Abstract

This paper presents the basic structural elements of the dome of Veliki Jastrebac, as well as the chronology and mechanisms of the deformational events responsible for its formation. It was determined that the dome of Veliki Jastrebac consists of two large sequences which are, in the vertical section, in the inverse position. The lower part is made of Late Cretaceous and Cretaceous-Palaeogene low-grade to medium-grade metamorphic rocks, which are intruded by Paleogene granitoid (probably the Vardar Zone), which are covered with a large overthrust consisting metamorphics of the Serbian-Macedonian Mass. The low-grade to medium-grade metamorphosed complex of Veliki Jastrebac, with the granitoid, represents a metamorphic core complex, exhumed by mechanisms of extensional tectonics in the Paleogene

Geometric deformation analysis in free geodetic networks: case study for Fruska Gora in Serbia

“…The north-eastern area of Fruška Gora is characterized by the presence of transcurrently right faults where the distribution of local values of the stress field is controlled by the local fault structures. The significant displacement magnitudes and the significant strain parameters, obtained here, are correlated to the reactivated existing structures which have been recognised in earlier geological and geophysical studies (Marović et al, 2007;Matenco and Radivojević, 2012;Toljić et al, 2013). It is important to say that the geodetic methods of deformation analysis used here provide mainly geometric information about the changes having occurred, where the interpretation of results and identification of causal forces belongs to other kinds of research, such as neotectonic ones, so that geophysical.…”

“…The first step is the independent, free adjustment of both measuring Fig. 1 Fruška Gora shown in the DEM of the Serbia area (dark frame); observations plan of GNSS vectors in passive geodetic network configuration (right); the faults separating significant neotectonic blocks and zones (Marović et al, 2007).…”

Cenozoic granitoids in the Dinarides of southern Serbia: age of intrusion, isotope geochemistry, exhumation history and significance for the geodynamic evolution of the Balkan Peninsula

“…Fig. 9), Koroneos et al (2010) and Cvetković et al (2007b) proposed emplacement during the early stages of extension related to the formation of the Pannonian basin, the Bukulja intrusion being located in the footwall of a major core complex exhumed in early Miocene times (Marović et al 2007). Hence, the location of these S-type granites at the southern margin of the Pannonian basin, their Early Miocene age, and their association with core complex formation all argue for them being located in the backarc area of the W-directed subduction of the European lithosphere beneath the Carpathians, widely invoked to explain extension and magmatism in the main part of the Pannonian basin (Csontos 1995;Seghedi et al 2004).…”

The balance between orogenic building and subsequent extension during the Tertiary evolution of the NE Dinarides: Constraints from low-temperature thermochronology

“…However, the effects of this inversion into the NE part of the Dinarides and its relationships with the predating extension in terms of exhumation are still a matter of debate (e.g. Marović et al, 2002Marović et al, , 2007aMarović et al, , 2007b. The research of this study aims to constrain the exhumation of the NE Dinarides by means of low-temperature thermochronology, analysing three key orogenic areas, i.e.…”
