摘要
新疆阿克陶县的木吉西铜矿床地处西昆仑的木吉乡—慕士塔格山断隆带,成矿受岩浆岩接触带构造的控制,已发现的铜矿脉与土壤地球化学异常相吻合,铜矿脉产状各异,形成一不规则的环状,矿化类型主要为含铜铁白云石脉,同时发现浸染状矿化等斑岩矿床的矿化线索。通过矿床成矿地质特征的阐述,对比江西大湖塘、安徽沙坪沟等特大型斑岩矿床的找矿经验,认为木吉西铜矿处于斑岩矿床外围或顶部的脉状矿体带,矿床具有寻找斑岩铜矿的潜力,应继续寻找浸染状斑岩型铜矿化的成矿信息。
The Mujixi copper deposit is located at Mujixiang-Mushitageshan faulted upfold belt in the weste Kunlun mountains.The ore is controlled by the contact zone of the magmatic rock.The copper ore veins encountered are coincided with the soil geochemical anomlies.The ore veins are varied in morphology occurring as a ring.Mineralization is dominated by Cu-bearing dolomite vein.However,dissemination of porphyry ore has been traced.Geological characteristics are described and can be correlated to those of Dahutang gigantic porphyry copper deposit in Jiangxi province and Shapinggou gigantic porphyry copper deposit in Anhui province thus it is considered that Mujixi copper deposit occurs as an ore vein zone located at top or surroundings of porphyry copper deposit and is potential to prospect porphyry copper ore and the disseminated ore tracing should be continued.
