摘要
云南永善县金沙厂铅锌矿矿体呈脉状、透镜状、似层状产出。矿区内的层间破碎带、断层破碎带以及地层褶皱构造之虚脱部位,是主要的容矿构造。矿体近矿围岩为震旦系上统灯影组白云岩、硅质白云岩、含磷白云岩。矿床具有上层状下脉状、上平缓下陡倾的成矿特点,属构造控制中低温热液型矿床。
The ore body of Jinshachang Pb-Zn deposit occurs as vein,Lens and stratoid in Yongshan County,Yunnan Province.The collapsed part of interlayer fracture zone,fault tectonic fracture zone and fold structure is the main ore-hosting structures.The near-mining surrounding rocks are dolomite,siliceous dolomite,and phosphorus-bearing dolomite of Dengying Formation in the Upper-Sinian System.The deposit has the characteristics which is upper layering,lower veining,and gentle and steep dip.The ore deposit genesis is medium-low temperature hydrothermal deposit which is controlled by structure.
