摘　　要：岩矿鉴定是现代矿床学研究中的重要组成部分,推动了矿床学向微观研究的进程,在现代地质勘查中应用越来越广泛。岩石薄片鉴定以岩石定名为主,矿石光片以矿石中金属矿物鉴定为主,进一步取得有用的物理化学参数,进而分析成矿作用以及对找矿勘查提供重要的指示。本文以某铜矿床的光片鉴定为例,通过反光显微镜下的研究,得出矿石中金属矿物以方铅矿、闪锌矿、含砷黄铁矿、毒砂等为主,车轮矿、斜硫砷铅矿和异极矿等次之。Rock ore identification is an important part of modern ore deposit science research,which promotes the process of ore deposit science to microcosmic research,and has been applied more and more widely in modern geological exploration.The identification of rock thin slice is mainly based on rock name,and the identification of metal minerals in ore light slice is mainly based on the identification of metal minerals in ore,so as to further obtain useful physical and chemical parameters,and then analyze the mineralization and provide important instructions for prospecting and exploration.In this paper,the light plate identification of a copper deposit is taken as an example,through the study under the reflective microscope,it is concluded that the main metal minerals in the ore are galena,sphalerite,arsenopyrite,arsenopyrite,and so on,and the next are chainite,plagiothium-arsenopyrite and heteropolar ore.
