| Abstract: | 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. |
