| Abstract: | Junhe Reyinsumu area in Inner Mongolia belongs to ErlianDongwuqi late PaleozoicMesozoic metallogenic belt in Inner MongoliaDaxing''anling in PaleoAsian metallogenic region. It is an important copper and polymetallic concentrated distribution area in China. 61 surface rock samples have been collected in this field survey, and 16 elements of Au, Ag, Cu, Pb, Zn, As, Sb, Bi, Hg, W, Sn, Mo, Cd, Co, Cr and Ni have been analyzed. Based on the information of geochemical distribution characteristics of elements in rocks, the contents of elements in rocks, the contents of elements in each rock zone, the enrichment and dispersion of elements in rocks have been analyzed. The combination characteristics of elements in rocks have been studied by factor analysis and cluster analysis, physical properties of element combination have been judged, the mineralization has been analyzed, and the direction of prospecting has been pointed out. At the same time, it is pointed out that this area has the prospecting potential for sulfide type Pb, Cu, Bi nonferrous metals and Cd, Co related to andesite. |
