摘要

广西三江县老堡铅锌矿床,为广西首次发现成型扬子型铅锌矿床,矿体呈层状、似层状产于震旦系上统老堡组硅质岩、陡山沱组白云岩层间构造中,与地层同步褶曲,矿石组分简单,金属矿物主要有方铅矿、闪锌矿,次为黄铁矿,非金属矿物主要有白云石、石英,重晶石、绢云母;围岩蚀变以硅化、碳酸盐化为主。成矿明显受三江同沉积断裂、震旦系老堡组硅质岩、陡山沱组白云岩、浅海-半深海闭塞还原环境的控制。
        Laobao Pb-Zn deposit in Sanjiang,Guangxi is the first huge Yangtzi type Pb-Zn deposit that is discovered in Guangxi.The ore bodies occur in lit-par-lit structure between silicalite of Laobao group and dolomite of Doushantuo group of upper Sinian system,and they fold synchronously with strata.The composition of the ores is simple.Metal minerals include galena,sphalerite(major) and pyrite(minor);nonmetal minerals include dolomite,quartz,barite and sericite.Wall rock alteration includes silicification and carbonatation.The mineralization is obviously controlled by the synsedimentary faults in Sanjiang,silicalite of Sinian Laobao Formation,dolomite of Sinian Doushantuo Formation,and neritic-bathyal block reducing environment.
