摘　　要：小腊铅锌矿位于钦杭成矿带南段,为一套海底喷流沉积成矿系列,喷流热水沉积矿床多被后期的岩浆热液成矿作用叠加改造。矿区最重要的蚀变为重晶石化,不同的重晶石成因具有不同的成矿指示意义。小腊铅锌矿具有岩浆热液作用叠加改造喷流沉积成矿作用的特征,深部找矿潜力较大。The Xiao La lead and zinc deposit is located in the south section of the qinhang metallogenic belt,which is a set of seabed jet sedimentary series,and the jet hot water deposits are mostly reformed by the later magmatic hydrothermal mineralization.The most important alteration in the mining area is barite,and different barite genesis has different metallogenic significance.The Xiao La lead zinc deposit has the characteristics of superimposed magmatic hydrothermal action and transformation of the exhalative sedimentary mineralization.
