| Abstract: | (U-Th)/He dating method is a new radiogenic isotope dating method rapidly developed in recent years,which has been applied widely in the research field of basic geology.At first,we simply present the(U-Th)/He dating principle and summarize its technique development and application results in geological research.Furthermore,we discuss the feasibility of(U-Th)/He dating in determining the forming age of nonmetallic-metallic ore deposit,the succeeding alteration and unroofing age of metallic ore deposit. |

| Keywords: | (U-Th)/He Isotope dating Ore deposit geochronology |
