摘要
新疆西准噶尔金矿成矿域是大区域内成矿单位,成矿域中所有金矿床(点)均产于地壳构造活动带(板块缝合线上).富含金的地幔物质沿深大断裂上升侵位,分熔,产生岩浆、火山活动、壳下重熔再熔、火山物质沉积变质作用.在漫长的华力西期经历反复多次的构造变动,形成超基性—基性火山-沉积-变质(类绿岩带)含金建造。
Western Junggar gold forming province is divided into three gold ore zones southward. They are a product of the collision between Junggar plate and Kazakhstan plate. All gold deposits in this region occur in a tectonically active belt. They are different in location and space, and so present different genesis types of deposits. According to the study of the regional geology of the gold metallogenic province, ore petrology, ore mineralogy, geochemistry (trace elements and stable isotope), etc., a conclusion can be made that all gold deposits in the three mineralizing zones are colsely related in genesis space and age. It belongs to a metallogenic series.
