摘要

Bor和Cukaru Peki是与白垩纪Timok岩浆杂岩在空间和成因上相关的世界级斑岩矿床。该研究旨在确定形成这些矿床的岩浆岩的年龄和地球化学亲和力。我们对Bor和Cukaru Peki矿床的岩浆岩进行了新的地球化学分析，表明它们包含了类似埃达克岩的成分，经历了角闪孔分馏和硫化物饱和过程。锆石年龄表明，Bor体系形成于84.5 ~ 82 Ma之间，Cukaru - Peki体系形成于86.5 ~ 85 Ma之间。

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

Bor and Cukaru 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 Cukaru 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 Cukaru Peki system was created in the age span between 86.5-85 Ma.
