摘要
云南会泽县小江铅锌矿矿体呈似层状、脉状、透镜状赋存于断层构造破碎带中,构造控矿明显,矿体围岩均为灯影组(Z_2dn)白云岩矿床成因为热液交代-充填型原铅锌矿床。断裂构造加上硅化、黄铁矿化、萤石化、斑马状白云岩化、重晶石化、等矿化蚀变是主要的找矿标志。
The orebody in Xiaojiang Pb-Zn deposit in Huize,Yunnan is stratoid,veined,lenticular in the fault fracture zone,ore control of structure clear.The wall rock of orebody is Dengying Formation(Z2dn)dolomitite.It is the hydrothermal metasomatic filling Pb-Zn deposit in genesis.The main prospecting criteria are the fault structure and the alteration of silicification,pyritization,fluoritization,zebra dolomititization,baritization,etc.
