摘要
乐红铅锌矿矿体呈脉状,赋存于断层构造破碎带中,矿体直接围岩为上震旦统灯影组第二段之硅质白云岩。矿石矿物以金属硫化物为主,脉石矿物以白云石为主,从矿物生成顺序看,该铅锌矿的成矿过程可划分为原岩沉积阶段、碎裂岩化阶段和成矿热液阶段。
The ore body ol Lehong Pb-Zn deposit is veined in fault structure fracture zone. The direct wall rock ol ore body is Upper Sinian Dengying Formation Member 2 silisic dolomitite. The main ore mineral is metallic sulfide, whereas the gangue is mainly the dolomite. According to the forming succession of mineral, the metallo- genesis of this Pb-Zn deposit can be divided into 3 stages of original sedimentation, fracture rock formation and hydrothermal metallogenesis.
