The Hatu gold deposit, locating in west Junggar of Xinjiang, is composed of quartz vein type orebody and alteration type orebody. The orebodies are hosting in tuff and basalt in Lower Carboniferous volcano-sedimentary rocks. The authors study the alteration-type orebody which mainly locates in the deep part of Hatu mine. Pyritization, arsenopyritization, carbonation, sericitization and chloritization are widespread in the alteration-type orebody. The essential gold mineral of Hatu deposit is native gold with average gold content of 91.2%. Native gold in the major auriferous minerals (pyrite and arsenopyrite) occurs in the intergranular, crevice and enclosure forms. The native gold-tetrahedrite-chalcopyrite-sphalerite assemblages can be enclosed by pyrite or fill the fractures of pyrite. The native gold-pyrite-chalcopyrite can be enclosed by arsenopyrite or fill the fractures of arsenopyrite
