摘　　要：采用矿山井巷工程地球化学勘探新技术方法,查明了大白岩矿段铜矿床主工业组分和共伴生有益组分。个旧以锡矿开发闻名,以其南部的卡房矿田大白岩矿段的变火山岩型铜矿床为例,总结了变火山岩型铜矿的主要特征,划分了成矿、成晕及成岩元素,探讨了矿床的主工业组分及其共伴生组分的成矿与成晕的关系。Using the tunnel engineering geochemical prospecting method, the authors found the main industrial components and accom-panying and associated useful components in the ore block of Dabaiyan. The meta-volcanics copper deposit in the ore block of Dabaiyan within the Kafan ore field in southern Gejiu was taken as an example, which is famous for its tin ore development. The main characteris-tics of meta-volcanics copper deposit were summarized, and deposit elements were classified into three types： ore-forming elements, halo-forming elements and diagenetic elements. The relationship between metallogeny and halo-forming of the main industrial compo-nents as well as accompanying and associated components of this deposit is discussed.
