There are several papers published in recent years about the relationship between "adakite" and mineralization. In a paper published in Vol.29, No.5 issue of 《Mineral Deposits》, Mr. Zhang Qi put forward a series of new ideas concerning the relationship between adakite and Au-Cu/W-Sn mineralization. In this paper, the author has advanced some different views on the definition of adakite, the proper scope for the usage of Yb-Sr diagram and the validity of adakite in prospecting. The research on ore deposits must be built on steady field work and comprehensive analysis. One basic principle of ore deposits research is to combine the field work and comprehensive analysis with experiments and tests.
