云南泸水县石缸河钨锡矿特征及找矿前景

THE FEATURE AND PROSPECTING POTENTIALITY OF SHIGANGHE W-SN DEPOSIT IN LUSHUI,YUNNAN

云南泸水县石缸河钨锡矿矿体呈脉状、透镜状赋存于断层构造破碎带中,构造控矿明显,燕山期-喜马拉雅期花岗岩侵入为钨矿的形成则提供了岩浆热液成矿物质。通过进一步的地质找矿,在石缸河矿区外围已揭露到了新的矿化带和钨、锡、铋组合地球化学异常,因此在矿区边部或深部隐伏岩体接触带,对寻找钨锡矿化具有较大找矿前景。

The orebody of Shiganghe W-Sn deposit in Lushui,Yunnan is Veined,lenticular in the fault fracture zone,ore control of structure evident.Yanshanian-Himalayan granite intrusion provide the magmatic hydrothermal metallogenesis material for W deposit.According to the further prospecting,we have found out the new metallogenesis zone and W-Sn-Bi assemblage geochemical anomaly around Shiganghe orefield.So,the contact of marginal or deep part of the buried rock body has very good prospecting potentiality of W-Sn metallogenesis.
