This paper deals in details with zircon mineralogy of two different types of mineralized granitoids (REE, RE tungstentin mineralized granitoid and copper, polymetal mineralized granitoid from eight rock masses with 30 artificial heavy concentrate samples in total) including physical properties of minerals, x-ray powder analysis,chemical analysis, infrared spectrometry and ESM etc. First,the geological occurrence and paragenious minerals of zircon in granitoids of two types of mineralization are discussed. Then the typomorphic characteristics of zircon from two different types of mineralized granitoids of Yanshang orogeny in South China are summed up on the basis of systematic sorting out and all-sided analysis of numerous test data. The results of investigatiions show that the zircon typomorphic characteristics of the above-mentioned two types of mineralized granitoids remarkably differ from each other. The significance of the two types of zircon typomorphic characteristics is emphasized in this paper. Furthermore, the controlling factors and formation mechanism of the zircon typomorphic characteristics are discussed. On this basis, some ore-prospecsing criteria in the diversed mineralized granitoids of Yanshang orogeny in South China are pointed out.
