摘　　要：近年来有关太阳系天体中等挥发性元素的研究掀起了一波浪潮。锌作为中等挥发性元素,其稳定同位素对于高温挥发过程具有很好的指示作用。因此,在行星科学领域锌同位素逐渐成为研究星云和行星演化的一个理想工具。本文系统地归纳了各类陨石和行星天体储库的锌同位素组成,并对不同种类的陨石以及地外样品(碳质球粒陨石、普通球粒陨石、顽火辉石球粒陨石、橄辉无球粒陨石、铁陨石、石铁陨石、月球陨石和Apollo样品、火星陨石、灶神星陨石等)中的锌稳定同位素研究内容进行了较全面的总结。主要包括不同陨石和行星锌同位素组成的控制因素以及锌同位素对太阳系内星云过程和行星过程的指示;同时,简要论述了锌同位素在太阳系形成和演化过程中的分馏机制,并立足目前的研究基础,探讨锌同位素在行星科学领域的研究前景和发展趋势。In recent years,the research on moderately volatile elements in solar system bodies has sparked a wave of interest.As a member of moderately volatile elements,zinc(Zn)and its isotopes are good indicators for tracing the high-temperature evaporation process.Hence,the Zn isotope is considered as an ideal tool to study the evolution of solar nebula and planets in the planetary science.Here,we have systematically summarized the Zn isotopic compositions of various meteorites and planetary reservoirs,and have provided a comprehensive overview on the zinc stable isotope researches of different types of meteorites and extraterrestrial samples(carbonaceous chondrites,ordinary chondrites,enstatite chondrites,angrites,iron meteorites,stony-iron meteorites,lunar meteorites and Apollo samples,Martian meteorites,Vesta meteorites,etc.).Those researches were mainly concentrated on the controlling factors of zinc isotope composition in different meteorites and planets and the indication of zinc isotopes for the nebular processes and planetary processes in the solar system.At the same time,we have briefly discussed the fractionation mechanism of zinc isotopes in the formation and evolution process of the solar system,and have explored the prospects and development trends of zinc isotope researches in the planetary science on the basis of previous researches.
