摘　　要：来龙铅锌矿属热液脉型铅锌矿床,矿体产于上三叠统三合洞组(T3s)灰岩层间破碎带中,矿体受断裂破碎带控制明显。围岩蚀变有硅化、白云石化、方解石化、炭化、褐铁矿化等。其中白云石化、方解石化、褐铁矿化与成矿较密切。Lailong Pb-Zn deposit is a hydrothermal veined pb-Zn deposit. The ore body is in the interbed fracture zone of Upper T Sanhedong Formation limestone, which is controlled evidently by the fault fracture zone. There are the alteration of wall rock, silicification, dolomitization, calcitization, carbonification, limonitization, etc. The dolomitization, calcitization and limonitization are related close to the metallogenesis.
