摘　　要：介绍了Zn同位素组成的表示方法及其化学分离与质谱测定方法,论述了Zn同位素在陨石、沉积物和沉积岩、火成岩、矿床和海水以及生物样品中的组成特征,以及生物有机作用、物理-化学作用对Zn同位素分馏的影响,阐述了Zn同位素在陨石和宇宙化学、古海洋学、全球气候变化研究中的应用现状与前景。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.
