埃塞俄比亚北部特拉喀密提VMS型铜锌多金属矿床地质特征与找矿标志

Geological characteristics and prospecting criteria of the Terakimti VMS type Cu-Zn polymetallic deposit in the northern Ethiopia

特拉喀密提铜锌多金属矿位于埃塞俄比亚北部成矿带矿产富集区,区内已发现与海相火山作用有关的块状硫化物矿床(点)6处。文章在野外地质调查和找矿勘查成果的基础上,结合收集到的地质矿产资料,系统地总结论述了特拉喀密提铜锌多金属矿地质特征、找矿标志,探讨了矿床形成环境、成因类型,认为该矿床属于黑矿(Kuroko)型VMS矿床,为该地区成矿预测和地质找矿提供了理论依据。

The Terakimti copper-zinc polymetallic deposit located in the northern part of Ethiopia, occurs at a major volcanic metaUogenie area, where six metal deposits related to submarine volcanism have been discovered recently. Based on the detailed filed investigation, exploration and previous geological data, the author systematically described the geological characteristics and prospecting criteria of the Terakimti deposit and discussed the tectonic environment and the metallogenic type. According to the study results, the authors consider that the Terakimti deposit is the Kuroko type VMS deposit. This perception provides a new theoretic basis for the metal- logenic predication and mineral exploration.
