| 摘 要： | 西藏玛圭铅锌多金属矿在冈底斯铅锌银成矿带已发现的矽卡岩型多金属矿床中处于最西段。通过目前的预查工作,在矿区内共发现有14条矿体,初步预测可达到中-大型矿床规模。冈底斯中东段目前研究程度已较高,而西段与之具有相同的良好的矽卡岩型多金属矿成矿地质条件,但发现的矿床却很少。玛圭矿床的发现为该成矿带向西延伸和扩大规模提供了依据,并增加了进一步向西寻找同类型矿床的信心。

| Abstract: | The Magui lead-zinc polymetallic deposit is at the west end of the skarn type lead-zinc polymetallic deposits found in the Gangdise lead-zinc-silver metallogenic belt. Through the current pre-investigation work, a total of 14 orebodies were found in the mining area. It is initially predicted that an intermediate-large deposit is attainable. The middle and eastern section in Gangdise possesses high level of study at present. Though the western section possesses low level of study, it has the same good skarn polymetallic ore-forming geological conditions; nevertheless, ore deposits were rarely found there. The discovery of the Magui deposit provides evidence for the westward extension of the ore-forming process and the expansion of the mineralization scale and also increases the confidence that the same kind of ore deposits might be found in westward direction. |
