Abstract: The natural types of deposits ought to be applied in gold exploration. Based on the critical characteristics of orebody,vein-type gold deposits may be classified into auriferous quartz,auriferous-altered rock,auriferous mylonite,adularia sericite quartz,and fine impregnated mineralization. The three-in-one elements of gold bearing formation,fracture system and hydrothermal process are ground preparation of ore-forming.
