摘要
布仑口铜矿带位于西昆仑中央隆起带中。赋矿地层为早震旦系塔什库尔干群片岩、片麻岩、白云岩。铜矿床以品位富、含矿层位稳定且与菱铁白云岩关系密切为特征。卡拉玛铜矿伴生Au、Ag元素(Au的品位大于1×10-6),小沙子沟铜矿富Ag。元素R型相关分析表明,矿化元素Cu与Au、Ag、Mo、As、Bi、Hg、Sb正相关。矿石黄铁矿δ34S为-5.20‰~+5.67‰。矿床是早期火山沉积。
The Bulunkou copper deposit located in the uplift of central western Kunlun is hosted in the schist, gneiss and dolomite of Taxkorgan Group of Lower Sinian System. The orebodies are characterized by rich ores, stable ore-bearing horizon and close relation to siderite-bearing dolomite. Au and Ag are associated in the Kalama copper deposit, and Ag is enriched in the Xiaoshazigou copper deposit. The correlation analysis shows a positive correlation between Cu and Au, Ag, Mo, As, Bi, Hg and Sb. The pyrite from the deposit shows 34S values of -5.2 and 5.67. The studies show that this deposit represents one that is of origin of early volcanic sedimentation and late superimposition by hydrothermal process.
