| 摘 要： | 新疆北部阿舍勒铜锌多金属矿床为海相火山岩型块状硫化物矿床,形成于晚古生代西伯利亚西南缘活动陆缘环境。在西伯利亚、哈萨克斯坦-准噶尔板块多阶段的俯冲、碰撞、拼合过程中,矿床所处的大地构造环境经历了多个开合演化阶段,为该矿床提供了良好的先天、临产及后天条件。成矿以喷气-沉积作用为主,其后经历了变质改造、岩浆热液叠加及表生氧化作用。矿床控制因素显示出“地层-岩控-构控和时控”多位一体的特点。同位素及微量元素研究表明,成矿物质具有多源性。根据陈国达历史-因果论大地构造学提出的多因复成矿床概念和时空四维兼顾研究思路,讨论了阿舍勒铜矿的多因复成矿床特征,厘定其为一个多因复成型矿床。

| Abstract: | The Ashele Cu polymetallic deposit in northern Xinjiang, which was formed in an active continental margin of SW Siberia in the late Paleozoic, is a marine volcanic massive sulfide deposit. At the course of subduction, collision and collage among the Siberia, Khazakstan and Junggar blocks, the geotectonic environment underwent a few evolutional stages, they provided good congenital, parturient and postnatal conditions for the deposit. Ore formation was dominated by exhalation-sedimentation, subsequently subjected to metamorphism reformation, superposition of magmatic hydrothermalism and supergenesis. The characteristic of “strata control-structural control-lithologic control” is quite apparent all over the mining area. Isotopic and trace elements data show that mineralizing materials are of multi-sources. Based on Chen Guoda’s historic-causationist geotectonics and the thought of four-dimensional space-time, the polygenetic compound metallogenic characteristics about the deposit is discussed, finally it is determined as a typical polygenetic compound deposit. |
