“…This zone also hosts the low-sulphidation deposit of Zlaće and the sediment-hosted Au mineralization Korkan-Bigar Hill [13,37]. In the last several years, occurrences of manganese ore were also reported in this part of the TMC, and they are interpreted as VMS/SEDEX-type of mineralization [13,19,38].…”

This study aims at better constraining the link between magmatism and metallogeny in the south-easternmost sector of the Bor Metallogenetic Zone (BMZ), where the world-class copper and gold deposit of Čukaru Peki was recently discovered. The obtained U/Pb zircon ages confirm the earlier knowledge that the major Cu–Au porphyry and epithermal mineralization in the BMZ is genetically related to the first volcanic phase (‘Timok andesite’; 85–90 Ma). However, the data also suggest that during this phase, two subgroups of andesite porphyry were formed; they are named volcanic phase 1A (V1A) and volcanic phase 1B (V1B). The V1A andesite (89–90 Ma) is plagioclase-hornblende phyric, holocrystalline and ubiquitously hydrothermally altered and/or mineralized, whereas the V1B (85–86 Ma) is hornblende-plagioclase phyric, holo- to hypocrystalline, fresh, and non-mineralized. According to our simplified model, the contrasting productivity of the V1A and V1B is explained by fluctuations during AFC (assimilation-fractional crystallization) processes of water-rich parental magma, which have controlled the order of crystallization of hornblende and plagioclase in the V1A and V1B andesite.

This study reports on the stratigraphic characteristics of the main units and indicates the link between magmatism and mineralization in the Bor Metallogenetic Zone (BMZ)-the Timok Magmatic Complex (TMC). Existing data are supplemented by the latest different systematic long-term geological and stratigraphic surveys and new and contemporary mineral exploration methods. The TMC extends on a continental crust composed of different types of the Proterozoic to the Lower Cretaceous units and consists of the volcanic/magmatic, volcanogenic-sedimentary and sedimentary rock packages. Sedimentary processes and magmatism were almost continuous throughout the Late Cretaceous. The sedimentation lasted from the Albian-Cenomanian to the Maastrichtian. Magmatism occurred in at least two phases from the Upper Turonian to the Upper Campanian: I volcanic phase-V1 (90-82 Ma), II volcanic phase-V2 (83-78 Ma), with a steady decrease in age from East to West. Cu-Au porphyry mineralization occurs between 87-80 Ma. The major epithermal and porphyry mineralization is related to the V1 magmatic phase predominantly developed in the easternmost part of the BMZ.
