摘　　要：通过野外地质调查采样、显微镜鉴定、扫描电镜观察和X射线能谱仪测试分析,对钦杭成矿带村前铜铅锌矿床的矿石物质组分做了系统的研究,首次在矿石中发现了自然界罕见的自然铝及锌铜互化物矿物。这两类矿物均具有独特的形成条件,对研究矿床成矿环境、形成条件、成矿物质来源具有重要的指示意义,表明矿床成矿初期为高温强还原、低硫逸度环境,成矿流体中有幔源物质混入。The Qinhang metallogenic belt is an important copper polymetallic ore-forming belt in eastern China, and the Cunqian Cu-Pb-Zn deposit is a typical skarn copper polymetallic deposit in this ore-forming belt. Through sampling based on field geological investigation, microscopic examination, SEM observation, X-ray energy spectrum analysis, and systematic study of material components of ores, the authors found for the first time rare native aluminum and Zn-Cu intermetallic compound in the ores. Both of these two types of metallic minerals have special formation conditions and are hence of important indicative significance for studying the metallogenic environment, formation condition and ore-forming materials of the Cunqian deposit. The results obtained by the authors show that the early metallogenic epoch was characterized by an environment of high temperature, strong reduction and low sulfur fugacity, with the addition of some mantle materials to the ore-forming fluids.
