摘要
江城县松山林铅锌矿矿体呈似层状、透镜状产于近东西向的断层破碎带中,矿体近矿围岩为下白垩统景星组(K_1j),矿石岩性为碎裂岩化的石英砂岩、粉砂岩、岩屑石英砂岩;构造控矿明显,该铅锌矿为热液型矿床。沿断裂带分布的地球化学异常是重要的找矿标志。
The orebody of Songshanlin in Jiangcheng is stratoid,lenticular in nearly EW fault fracture zone.The wall rock near orebody is Lower Cretaceous Jingxing Formation( K1 j). The ore-bearing rock is fractured quartz sandstone,siltstone,lithic quartz sandstone. The ore control of structure is clear. It is a hydrothermal Pb-Zn deposit. The geochemical anomaly along the fault zone is the important prospecting criteria.
