%X 在自然界中锆石稳定性好，可以有效保存源区的原始信息，从而使得锆石成为国内外学者研究的重要矿物。通过对不同成因锆石(岩浆锆石、变质锆石、热液锆石)的晶型、内部结构、包裹体特征以及微量元素特征进行总结和评述，在不同的环境下锆石所形成的结构类型有很大的差异。简述了4种(ID-TIMS、SIMS、LA-ICP-MS以及LA-MC-ICP-MS) U-Pb同位素定年测定方法的基本原理、优点和不足。此外结合实例，运用不同成因锆石的定年结果，结合锆石矿物学和区域地质背景将得出的年龄合理的应用于地质过程中。<br />
Zircon has good stability in nature, which can effectively preserve the original information of the source area, thus making zircon an important mineral studied by scholars at home and abroad. Through the summary and comment on the crystal form, internal structure, inclusion characteristics, and trace element characteristics of zircon of different genesis (magma zircon, metamorphic zircon, hydrothermal zircon), the structural types of zircon formed by zircon are very different in different environments. The basic principles, advantages, and disadvantages of four (ID-TIMS, SIMS, LA-ICP-MS, and LA-MC-ICP-MS) U-Pb isotope dating methods are briefly described. In addition, combined with examples, the dating results of zircon of different genesis are used, combined with zircon mineralogy and regional geological background, the age obtained is reasonably applied to the geological process.
