Abstract:

Pyrite is one of the main Au-carriers in the Zhaishang gold deposit.The pyrite in the rock are fine and strawberry-like or coccus-like,globe-like,cube-like pyrite.The pyrite in the rock are thick and big,mineral form as cube,pyritohedron,xenomorphic granular, small veins.Pyrites of mineralization are poor in iron (Fe)=45.98%,sulfur (S)= 51.69%.S has been replaced by As,Sb,Fe has been replaced by Ni、Ag.The mode of occurrence of Au is self-existent in the pyrites.Au-carriers in the those strawberry-like,cube-like pyrite less than in those pyrites mineral form as cube,pyritohedron,xenomorphic granular,small veins.Au,As has the negative correlation characteristic feature in different pyrite.Those pyrites as overgrowth rim,in the first rim,third rim,fives rims are rich of gold, while in the core,second rim,fourth rim,and sixth rim are poor of gold,the relationship between Au and As is positive correlation.

Key words: Carlin type gold deposit, Pyrite, Gold mineralization, Zhaishang gold deposit, Western Qinling
