摘　　要：锆石作为一种稳定性强、封闭温度高的副矿物,广泛存在于各类岩石中,且不同地质成因环境下形成的锆石通常表现出不同特征。通过分析前人的研究,本文主要对岩浆锆石、热液锆石、变质锆石三类不同成因锆石的内部结构、包裹体类型、地球化学特征以及年代学意义作出系统的总结,以期为今后分析锆石成因类型、锆石定年提供一定借鉴。As a kind of accessory mineral with strong stability and high sealing temperature,zircon widely exists in all kinds of rocks,and the zircons formed in different geological environments usually show different characteristics.Through the analysis of previous studies,this paper mainly summarizes the internal structure,geochemical characteristics,inclusion types and geochronological significance of magmatic zircon,hydrothermal zircon and metamorphic zircon,hoping to provide some reference for the future analysis of zircon genetic types and zircon dating.
