%X Located in the Namling Country of Tibet, the Pusangguo copper polymetallic deposit is a skarn-hydrothermal vein type deposit and lies in the eastern part of the Gangdise belt. The ore mineral compositions and the modes of occurrence of Co-Ni were systematically studied in this paper. The ores are made up of some complex medium-low temperature hydrothermal minerals, such as chalcopyrite, pyrite, galena, marmatite, pyrrhotite and covellite. The modes of occurrence of Co-Ni revealed by means of microscope and scanning electron microprobe indicate that Co-Ni are mainly present as cobaltite (Co 17.87%, Ni 12.66%); and are also scattered in ferrous sulfides, such as chalcopyrite (Co 0.04%, Ni 0.08%), pyrite (Co 0.40%, Ni 0.20%), sphalerite (Co 0.14%, Ni 0.06%), and pyrrhotite (Co 0.79%, Ni 0.18%), in which Co-Ni exist in the form of isomorphous replacement of Fe. The results indicate that there exists a new type of mineralization in the Gangdise belt, and this discovery sup-plies important information for further exploration.
