摘要
文章根据铜厂沟金矿的矿区地质特征、碎屑岩岩石地球化学特征、英云闪长岩岩石化学特征、稀土元素地球化学特征等的研究,认为寒武纪碎屑岩原始沉积环境属于海洋岛弧优地槽环境复理石沉积物,复理石沉积物及超基性岩石为主要的矿源岩。提出英云闪长岩脉与超基性岩及绿泥石片岩边缘接触带中构造破碎带是有利的控矿构造部位,含黄铁矿硫化物石英脉是有利的找矿标志。
Based on mine geology, petrology and geochemistry of clastic rock, tonalite petro - chemistry, and rare earth elements geochemistry in the Tongchanggou gold deposit, it is concluded that original sedimentary environment of Cambrian clastic rocks belongs to ocean island arc geosyncline environment flysch sediments and flysch sediments and uhrabasie rocks are main source of ores. It is pointed out that fractures in the contacting zone between tonalite and ultrabasic rocks or chlorite schist are favourable sites for ore - controlling. Pyrite - bearing sulfide quartz veins are favourable prospecting criteria.
