云南宁蒗县白牛厂金矿成矿地质条件及找矿模式

THE GEOLOGICAL CONDITIONS AND PROSPECTING MODEL OF BAINIUCHANG AU DEPOSIT IN NINGLANG,YUNNAN

云南宁蒗县白牛厂金矿断层构造控矿特征十分明显,按产出特征可分为两类:一是产于北东向顺层构造(F8)破碎蚀变带中的似层状、透镜状矿体;二是沿北北西向断裂带充填的脉状矿体。其成因类型属断层破碎带控制的中-低温热液型矿床。

The ore control of fault of Bainiuchang in Ninglang,Yunnan is very clear.According to the occurrence feature,It can be divided into 2 types.One is the stratoid,lenticular orebody in the NE bedding structure(F 8)fracture alteration zone;another is the veined orebody filling in the NNW fault zone.It is the middle-low T hydrothermal deposit controlled by the fault fracture zone in genesis.
