| 中文摘要: |
| 塞尔维亚佩吉铜金矿床位于世界著名的特提斯欧亚成矿带西端的 Timok岩浆杂岩带南部。该矿床由上部高硫型铜金矿化和下部斑岩型铜金矿化组成，矿化主要赋存在下部安山岩中。文章通过分析岩石多元素地球化学特征，并结合地质编录，认为下部安山岩并非单一岩性，而是由三种不同的岩性组合而成。其中 LA-2系列安山岩是主要的赋矿围岩，具有高 V/Sc、低 Sc和高 Sr、低 Y、高 Sr/Y比值的特征，显示该期岩浆可能为富铜的斑岩岩浆，区内的金铜矿化与该期岩浆关系最为密切。多元素地球化学特征分析可作为火山岩地层岩性和含矿性识别提供参考。 |
| 英文摘要: |
| Cukaru Peki Copper-gold deposit is located in the south of the Timok magmatic complex at the western end of the world-renowned Tethyan Eurasian metallogenic belt. The deposit comprises an upper high-sul.dation mineralization zone and an underlying porphyry-style mineralization zone. The orebody occurs mainly in the lower andesite unit. The lower andesite unit may be composed of three di.erent sub-units according to the multi-element geochemical characteristics and geological logging of the rocks. The characteristics of the main ore-bearing rock unit LA-2 are high V/Sc, low Sc and high Sr, low Y,and high Sr/Y ratio, which indicates a copper-rich porphyry magma source, and a close relationship between the magma and the cooper-gold mineralization in this region. The analysis of multi-element geochemical characteristics can provide reference for the identi.cation of lithology and ore-bearing property of volcanic strata. |
