摘　　要： 斑岩铜矿研究之所以方兴未艾,一则是其特殊的蚀变分带性,二则是其成矿专属性。本文对中国斑岩铜矿的时空分布特征、岩浆源区特征、岩石学及地球化学特征等若干问题进行了总结,并归纳中国斑岩铜矿的成矿特征:主要分布于北部成矿域、东部成矿域和西南部成矿域;年代上以中生代最为重要;大陆边缘(包括陆内古板块边缘)和岛弧环境为其产出的主要大地构造环境;原始岩浆起源于下地壳或上地幔,或壳幔混染并受上部地壳的混染;成矿物质主要来自下地壳或上地幔,具备典型的矿化蚀变分带。最后参考两位著名斑岩成矿带研究科学家:秦克章教授和芮宗瑶教授的报告,结合笔者野外工作心得,总结出斑岩铜矿的形成前提与找矿标志,以期为地矿部门探矿找矿提供一些理论指导。 The study of porphyry copper deposits is in the ascendant,one is its special alteration zonation,the other two is its metallogenic specialization.This paper summarizes some problems of temporal and spatial distribution characteristics,the characteristics of porphyry copper Chinese magma source,petrology and geochemistry,and summarize the metallogenic characteristics of porphyry copper China：mainly distributed in the North Eastern metallogenic domain,metallogenic domain and southwest metallogenic domain;years on behalf of the most important in the Mesozoic continental margin（;including the ancient land plate edge） and the output of the main island arc tectonic environment;primitive magma originated from the lower crust or upper mantle,or contamination of crust mantle mixing and upper crust;ore-forming materials are mainly derived from under the crust or upper mantle,with typical mineralization alteration zone.The last reference to research scientist two famous porphyry metallogenic belt：Professor Qin Kezhang and Professor Rui Zongyao＇s report,combined with the field work experience,summed up the premise for the formation and prospecting of porphyry copper deposits,in order to provide some theoretical guidance for the Department of Geology and mineral exploration prospecting.
