The confirmation of metallogenic age is the focus of modern deposit research. Based on the decay pattern of natural radioactive isotopes
isotope dating can get the age of rock or mineral by calculating the ratio between radioactive parent isotopes and the constant production of stable isotopes in rock or mineral. The importance of isotopic dating method in the study of metallogenic age is increasing gradually. In this paper
we summarize several commonly methods of isotopic dating in view of theory and experimental techniques. We analyze advantages and disadvantages of isotope dating such as U-Pb
