云南会泽金红铅锌矿区构造及地球化学特征

Tectono-geochemical Characteristics of Rutile Lead&Zinc Orefield in Huizein Yunnan

阐述了构造地球化学基本理论与内容及该区构造化学工作方法及特征,指出了构造地球化学异常是进行隐伏矿定位预测的重要依据。在该区选择了三条控矿构造,分析了其地球化学特征,其能够推断构造产状、指示成矿流体方向、提供矿床成因的有关信息,对岩石地球化学特征进行了对比分析,定位了找矿靶区,验证了此方法在该区找矿实践的有效性。研究证明:构造地球化学对隐伏矿床的定位预测和评价有着重要的指导意义。

Tectonicgeochemical prospecting method was applied to the deep prospecting practiceofHuize rutile lead and zinc mine in this study. The basic theoryandcontentsof tectonogeochemistry, and itsmethod and characteristics weres- tated.We argued that tectonic geochemical anomalies was the important basis for location prediction of hidden ore. Wechose three ore--controlling structures in the area, and described its geochemical characteristics. Tectonic geo- chemistry wasthoughtto be able to infer structure occurrence, indicate direction of ore--forming fluid, and provide information about the deposit formation.The comparison and analysis had been madeon the rock geochemical charac- teristics, which verified each other.Wepositioned the prospecting target areasand verified the validity of this method in prospecting practice in this area. Tectonic geochemistry for concealed deposit location prediction and evaluation had important guiding significance.
