摘要
新疆东戈壁斑岩型钼矿床是西北地区发现的第一个特大型钼矿床,矿床产于下石炭统浅变质碎屑岩夹火山岩中,位于雅满苏大断裂附近。文章通过分析含矿脉体之间的交切关系及生成先后顺序,将东戈壁钼矿成矿期热液作用划分为4个阶段;根据金属矿物之间的穿插、交代、共边关系,确定了矿物生成的先后顺序。
East Gobi molybdenum deposit in Xinjiang is the first super-large deposit discovered in north- west China. It is located near the Yamansu fault and occurrs in low grade metamorphic Lower Carbonifer- ous clastic rock intercalated with volcanic rocksl. According to cutting relation of ore veins hydrotrhermal mineralization in the deposit is divided into 4 stages and mineral paragenesus is determined on basis of cut- ting, replacement and edge share relation of the minerals.
