摘　　要：自然重砂及其组合蕴含着丰富的源区岩性体信息,为找矿勘查提供了丰富的矿源信息。已有地质勘查及研究主要集中在金、钨锡矿等,而对铜铅锌矿等其他矿种研究较少。针对铜铅锌矿种及其不同成因的矿床开展研究,通过普朗地区自然重砂矿物的类型及分布特点开展综合对比研究,挖掘其所蕴含的铜多金属成矿作用信息及找矿意义。普朗地区自然重砂矿物及其组合成片集中分布,其异常对已知区内铜多金属矿床具有良好的响应,体现出铜多金属成矿模式及成矿作用特点,反映具有成因意义的成矿作用信息,对区域矿产勘查具有良好的指示意义。Heavy minerals and their combination contain lots of source lithological units and provide abundant information of ore source. Geological prospecting and studies are chiefly focused on gold, tungsten ant tin, but less on copper, lead and zinc, etc. This paper studies the Cu-Pb-Zn deposits and their genesis, compares their heavy mineral types and distribution in Pulang area, and finds out the copper mineralization and indication of prospecting. The heavy minerals and their combination are clustering, their anomalies are responsive to copper deposits, reflecting copper mineralization model and metallization and revealing metallization information of genesis, which is of indication to regional mineral resources prospecting.
