摘要： 宝山铜铅锌多金属矿床位于我国南岭成矿带中段北缘，是南岭成矿带中的重要类型之一。宝山矿床具有明显的水平分带性，即以花岗闪长斑岩为中心的铜钼矿化，周边是铅锌银矿化。本文通过对宝山铜铅锌多金属矿床中的石榴子石、透辉石、黄铁矿、闪锌矿等矿物进行矿物学研究及电子探针测试分析，归纳总结出：宝山铜铅锌多金属矿床成矿期次为矽卡岩阶段、退变质与氧化物阶段、硫化物阶段；矿床石榴石端员组分总体以钙铁榴石（23.48%~90.39%）为主，其次为钙铝榴石（5.81%~71.27%）；辉石的成分端员以透辉石（Di61-95）为主，石榴子石成分和透辉石组分与世界上典型矽卡岩型铜矿的石榴子石和透辉石组分十分相似，属于典型的矽卡岩型铜矿床。从宝山铜铅锌多金属矿床硫化物中黄铁矿、闪锌矿矿物成分组成可以看出，该矿床硫化物为岩浆热液成因，并呈现出北东向比南西向成矿温度高的特征。

Abstract: The Baoshan Cu-Pb-Zn polymetallic deposit is located in the central Nanling mineralization zone, and is an important type of deposit in the Nanling polymetallic deposit belt. The Baoshan Cu-Pb-Zn polymetallic deposit shows the horizontal mineralized zoning clearly. Its zonation is comprised of Cu -Mo belt and Pb-Zn-Ag belt at the mining area from the middle to the periphery. In this research, the mineralogical study and electronic detection tests on the garnets, diopsides, pyrites, and sphalerites in the Baoshan Cu-Pb-Zn polymetallic deposits were conducted, and the mineralization was summarized as the skarn, retrograde and oxide, and sulphide stages. The garnet endmembers are mainly andradite(23.48%-90.39%)and followed by grossular(5.81%-71.27%);Pyroxenes are mainly diopsides(Di61-95). The mineral characteristics of garnet and diopside in the skarn are similar to those in typical Cu skarn all over the world. The composition of the pyrite and sphalerite in the sulfides of the Baoshan Cu-Pb-Zn polymetallic deposit indicates that the sulfides in the Baoshan Cu-Pb-Zn polymetallic deposits were from a magmatic hydrothermal source, and is characterized by a higher temperature in the northeast than in the southwest.
