摘要：

The study of Mg isotopes has been carried out for about 40 years since 1970 s. With analytical progress, the study is not only limited to the excess of 26Mg due to decay of short-lived 26Al in prinitive meteorites, also extended to mass-de-pendent fractionation of Mg isotopes in meteorites and terrestrial rocks. This paper reviews recent development in Mg isotope researches.
