留龙金矿存在两种不同类型的金矿体，一类为毒砂石英脉；另一类为铅锌硫化物石英脉。它们都受上施组火山沉积凝灰岩中近南北向断裂控制，具有不同的矿物组合、成矿温度和同位素组成。毒砂石英脉形成于１４０～２２０℃，δ＿（３４）Ｓ的值—０．０４‰～—１．０４‰，铅同位素组成与变沉凝灰岩一致，成矿流体以大气降水为主，是加热了的天气降水热液改造围岩而形成的改造型矿体。铅锌硫化物石英脉形成于２６０～３２５℃，δ＿（３４）Ｓ值—２．３５‰～０．８５‰，铅以加里东期岩浆源铅为主，混入了部分毒砂石英脉中的铅，成矿流体以岩浆水为主，是岩浆热液沿断裂充填，交代毒砂石英脉而形成的复合成因矿体。
There are two different types of gold deposits in the Liaolong gold deposit, one is poisonous quartz quartz veins and the other is lead-zinc sulfide quartz veins. They are controlled by nearly north-south faults in the volcanic sedimentary tuff of the Shangshi Formation and have different mineral assemblages, metallogenic temperature and isotopic composition. The arsenopyrite quartz vein formed at 140-220 ℃ with δ 34 S value ranging from -0.04 ‰ to -1.04 ‰, and the Pb isotopic compositions were consistent with those of variable tuff. The ore-forming fluid was dominated by atmospheric precipitation and was heated The weather of the hydrothermal hydrothermal transformation of the surrounding rock and the formation of modified ore body. Pb-Zn sulfide quartz veins were formed at 260-325 ℃ and δ 34 S values -2.35 ‰ -0.85 ‰. Lead was dominated by lead in the Caledonian magmatic source and mixed with part of the virgin quartz veins Lead and ore-forming fluids are dominated by magmatic water, which is a complex genetic ore body formed by the magmatic hydrothermal fluid filling along faults and dealing with toxic quartz quartz veins.
