新疆库科西鲁克一带金属矿山特征与成矿关系探讨

Discussion on the Geological Characteristics of Metallic Deposits in Kukexiluke,Xinjiang and Their Metallogenic Relation

在1∶50000区域地质矿产调查中,运用新的成矿理论和有效的找矿手段,在库克西鲁克一带发现数个矿点,这些矿点涉及的矿种较多,有Au,Ag,Cu,Pb,Zn,Mo,W和Fe等。它们受区域性成矿断裂——库科西鲁克断裂的控制,分布在岩体边缘接触带的元古-古生界变质岩中,分布区呈带状展布且较为集中。从矿区岩体人工重砂、围岩微量元素和主要矿点及其围岩的稀土元素等特征出发,初步探讨了矿体和围岩的成矿成因关系,并初步指出了卡拉库鲁木岩体可能为该矿区一些矿点富集成矿提供了物质来源。

In a 1：50 000 regional geological and mineral resources survey by new metallogenic theory and effective prospecting means, several mineral occurrences involving not a few types of metals such as Au, Ag, Cu, Pb, Zn, Mo, W and Fe were discovered in Kukexiluke. These deposits are controlled by a regional ore-forming fault-Kukexiluke fault and distributed in a belt-shaped extension and concentrated way in the metamorphic rock of Algonkian and Palaeozoic Erathem. The authors discuss preliminarily the metallogenic relations between the orebodies and the country rocks in terms of the rockmass artificial heavy placer of ore district, trace elements of country rock, main mineral occurrences and their rear earth elements, and point out in a preliminary way that Kalakulumu rockmass may be the substance source for the ore formation of some mineral occurrences in this ore district
