The process of rollback of the subducted oceanic crust in the Carpathians and the Aegean area (Rhodope Massif) induced local clockwise rotation of the Dinarides and caused the sharp bend of the Sava suture zone south of Belgrade in map view (Figure 2) as documented by paleomagnetic studies (Lesić et al, 2019).…”

The Karavansalija Mineralized Center at the Rogozna Mountains in SW Serbia: Magma Evolution and Time Relationship of Intrusive Events and Skarn Au ± Cu–Pb–Zn Mineralization

et al. 2022

The Karavansalija Mineralized Center (KMC) with its Au–Cu skarn mineralization associated with the Rogozna Mountains magmatic suite in southwestern Serbia belongs to the Oligocene Serbo-Macedonian magmatic and metallogenic belt (SMM-MB). Samples from intrusive and volcanic rocks at the KMC show typical arc signatures of subduction-derived magmas through enrichment in large-ion lithophile elements (LILE) and depletion of high–field strength elements (HFSE). The magmas developed a high-K (calc-alkaline) fractionation trend and evolved toward shoshonitic compositions. Whole-rock trace element data suggest plagioclase-absent, high-pressure amphibole ± garnet fractionation that generates adakite-like hydrous magmas during evolution in lower crustal magma chambers. Zircon LA–ICP–MS and high-precision CA–ID–TIMS dating together with zircon trace elements and Hf isotope measurements were carried out in order to couple the geochronologic and geochemical evolution of the KMC. The results suggest that magmatism starts around 29.34 Ma with granitic to rhyodacitic subvolcanic intrusions followed by a more evolved magmatic intrusion that was emplaced into Cretaceous limestone, generating a widespread skarn alteration at ca. 28.96 Ma. After a period of quiescence of about 1.2 My, either another magma body evolved or the same upper crustal magma chamber was recharged and also likely partly reactivated older plutonic rocks as indicated by xenocrysts. The REE ratios shift from apatite, titanite ± amphibole-dominated fractionation of the older magmatic event to crystallization of allanite, efficiently depleting the LREE and Th/U in the younger upper crustal magma. After a lamproite-like melt was injected, the increased heat and fluid pressure led to the expulsion of a quartz-monzonite porphyritic stock at ca. 27.72 Ma, strongly interacting with the skarns and established a fertile hydrothermal system. Soon after a non-mineralized second pulse of some porphyry dykes cut the previous phenocryst-rich “crowded” porphyries and skarns at ca. 27.60 Ma, thus bracketing the maximum timespan of ore mineralization to about 112 ± 45 Ka. Increased contribution of a lamproite-like melt is inferred from the presence of phlogopite micro-phenocrysts, phlogopitization of biotite, and diopside clusters in the latest porphyry dykes. There is a trend of increased crustal assimilation from the oldest volcanic phase to the emplacement of the youngest porphyry dykes recorded by ɛ-Hf of the zircons. Oligocene occurrences of significant base metal mineralization within Serbia, northern Macedonia, and Greece, e.g., Crnac, Rudnik, Veliki Majdan, Stratoniu, or the Cu–Au porphyry at Buchim (northern Macedonia), are all associated with trachy-andesitic (quartz latitic) porphyry dykes, which originated through post-collisional tectonic settings or upper plate extension involving reworking of crustal arc-derived rocks and partial melting of the mantle wedge. This study demonstrates that on the basis of field relationships and the application of high-precision CA-ID-TIMS zircon age data, pulses of porphyry dykes of a 10ka age range can be distinguished, and the timing of mineralization can be parenthized.

“…The present‐day change in the Sava Zone strike taking place between the Fruška Gora and Belgrade area can be correlated with opposite‐sense post‐20 Ma rotations (counter‐clockwise in the E–W segment in Fruška Gora and westwards and clockwise southwards, Figure 8a, Lesić et al, 2007, 2019; Márton et al, 1999, 2022), and with different Late Cretaceous tectonic transport directions in the E–W and N–S oriented segments of the Sava Zone (top‐S and top‐SW, respectively, Toljić et al, 2013, 2018 and this study). These associations indicate that the Sava Zone oroclinal bending occurred during the post‐20 Ma period.…”

Towards resolving Cretaceous to Miocene kinematics of the Adria–Europe contact zone in reconstructions: Inferences from a structural study in a critical Dinarides area

et al. 2022

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 strike-slip fault zone. We provide a solution to the debate by a structural and kinematic study in a key area located in central Serbia along the Europe-Adria orogenic suture of the Sava Zone. The results demonstrate that large-scale, top-SW, in-to out-of-sequence thrusting is the dominant mechanism that deformed the observed accretionary wedge-trench sediments during the Late Cretaceous subduction of the Neotethys Ocean and the ensuing Adria-Europe collision. The subsequent Oligocene-Miocene extension of the Pannonian Basin was associated with oppositesense rotations of different Sava Zone segments, which created the observed ~80° oroclinal bending.
