| 摘 要： | 冷水北沟铅锌矿床赋存于元古界栾川群和管道口群内,矿体受断裂破碎带及矽卡岩带的控制。矿石类型可分为热液脉型和矽卡岩型,矿体围岩蚀变强烈。根据矿床地质-地球化学特征,结合矿石的矿物共生组合、铅和硫同位素组成及成矿年龄、包裹体成分及特征,认为该矿床的矿源为岩浆岩,成矿溶液主要来自岩浆水和大气降水的混合溶液,矿床成因类型属中高温条件下形成的热液脉型-矽卡岩型矿床。 |
| 关 键 词： | 地球化学 热液脉型 矽卡岩型 矿床成因 冷水北沟 |

| Abstract: | The Lengshuibeigou lead and zinc deposit occurs in Proterozoic Luanchuan Group and Guandaokou Group,with ore bodies strictly controlled by the ductile shear zone and the skarn zone.The lead-zinc ores can be classified into the hydrothermal vein type and the skarn type with strong wall rock alteration.It is held that the mineralization resulted from the magmatic activity,as evidenced by the features of ore geology,geochemistry,mineral assemblage,lead and sulfur isotope,mineralization age and composition of inclusions in minerals.The ore-forming solution was a mixture of magmatic water and meteoric water.The deposit is genetically of the hydrothermal vein type and skarn type formed at medium-high temperature. |
| Keywords: | geochemistry hydrothermal vein type skarn type metallogenesis Lengshuibeigou |
