New insights on the geochemical affinity and age of mineralized rocks in Timok magmatic complex, East Serbia

Abstract

Bor and Čukaru Peki are world-class porphyry deposits spatially and genetically associated with the Cretaceous Timok magmatic complex. This research was conducted to determine the age and geochemical affinity of the magmatic rocks that formed these ore deposits. Our new geochemical analyses of magmatic rocks from Bor and Čukaru Peki deposits imply they comprise adakite-like compositions that have undergone the amphibole fractionation and sulphide saturation processes. The zircon ages indicate that the Bor system was formed in the age span between 84.5–82 Ma, while the Čukaru Peki system was created in the age span between 86.5–85 Ma.
