Geochemical characteristics of concealed Cu-PGE rich ore body, the Jinchuan deposit, northwestern China
1 IntroductionJinchuan Deposit located in Jinchang, Gansu, northwest China, is the worlds third largest being exploited magmatic Cu-Ni sulfide deposit, which contains seventeen elements such as Co, Au, Ag, PGE, besides Cu and Ni (S.G.T., 1984). The total proven ore reserve and Cu-Ni metallic reserve are respectively 550 million tons of ore, 5.58 million tons of Ni metallic quantity and 3.54 million tons of Cu metallic quantity. The average contents of Pt, Pd, Au and Ag are respectively 0.20ppm, 0.12ppm, 0.08ppm and 3.2ppm. It has been prospected and exploited for more than fifty years since discovered in 1952, whose part rich ore bodies have gradually been depleted. The phenomenon of resource crisis in some segments of the Jinchuan Deposit begins to emerge. Some scaled concealed ore bodies in its deep and border during exploiting and prospecting have been found.
