【Abstract】 This paper introduces the compositional expression of Zn isotope and its chemical separation and analytical techniques by mass spectrometer,along with a review of its compositional features in meteorite,sediments and sedimentary rocks,igneous suites,ore deposits,sea water as well as biological samples,respectively.In addition,the paper discusses Zn isotopic fractionations resulted from biological-and organic activities,physical-and chemical variations in environments.Finally,it summarizes the present applications of Zn isotope in the fields of astrolithology,cosmochemistry,paleo-oceanography and global climate evolution and their potential roles in these studies as well.更多还原
