Abstract:

Make a systematic summarize of the kind and size of the Au mineral, content of the Au mineral and the exist form of Au. Thought the study of comparing the content of Fe2O3 and Au in the limonite, demonst rating the content of Au and As in the arsenopyrite, discussing the relation between characteristic of pyrite and mineralization of Au, relation of Au,et al,draw a conclusion that Maquan gold deposit main mineral are limonite, arsenopyrite, pyrite ,minor mineral are quartz,et al. Ag in the mineral is from the mineral of Sb and Pb. Seeking on the earth’s surface, mineralization of limonite can be looked as the symbol,into the deepth , arsenopyrite, pyrite can be looked as the symbol.

Key words: limonite, arsenopyrite, pyrite, mineral of Sb and Pb
