浅析新疆西昆仑布仑口铜矿带地质特征及找矿标志

Analysis on geological characteristics and prospecting criteria of the western Kunlun copper belt in Western Xinjiang

西昆仑地质构造复杂,是我国重要的成矿带之一。本文笔者主要对西昆仑布仑口铜矿带地质特征及找矿标志进行研究与分析。该铜矿带就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。铜矿受地层层位、岩性、构造控制,铜矿床以品位富、含矿层位稳定且与菱铁白云岩关系密切。该铜矿带典型铜矿床卡拉玛铜矿伴生Au、Ag,小沙子沟铜矿富Ag。矿床是早期火山沉积、后期构造热液叠加改造形成的。

To tectonics of West Kunlun complex, is one of China’s important metallogenic belt. In this paper, the author mainly studies and analyzes the geological characteristics and prospecting criteria of the western Kunlun copper belt. The copper belt is located in the west of Kunlun central uplift belt, ore formation is early Sinian Tashikuergan group schist, gneiss and dolomite. The copper deposit is controlled by stratigraphic horizon, lithology and structure, and the copper deposit is closely related to the siderite dolomite, which is rich in grade and ore bearing horizon. The copper belt of typical copper deposits of Au and Ag Kalama copper deposits, small sand ditch copper rich Ag. The deposit is formed by the early volcanic sedimentary and later hydrothermal superimposition.
