Because nebular condensation occurred with temperature descending slowly, the forms of solar nebular condensation is dependent on the relationship between the pressure of nebular and‘triple point’ of nebular matter.

With analytical progress, the study is not only limited to the excess of ^26Mg due to decay of short-lived ^26Al in primitive meteorites, also extended to mass-dependent fractionation of Mg isotopes in meteorites and terrestrial rocks. This paper reviews recent development in Mg isotope researches.展开更多

文摘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 primitive meteorites, also extended to mass-dependent fractionation of Mg isotopes in meteorites and terrestrial rocks.
