摘要
锂(Li)同位素在自然界中的比值范围变化很大,轻、重Li同位素之间的分馏非常显著,对地球化学作用过程具有很强的指示性,因此作为新兴的非传统同位素,目前已被广泛应用于示踪各种地质作用和物质迁移过程。本文介绍了自然体系中锂同位素的基本特征和分析测试方法进展,系统阐述Li同位素在表生地质作用和内生地质作用研究中的实际应用和理论原理,以期深化对Li同位素体系的认识,推动新兴同位素方法在我国地学领域的应用研究。
The ratio range of lithium isotopes in nature varies greatly,and the fractionation between light(6Li)and heavy(7Li)isotopes is very significant,which is a strong indicator of geochemical processes.Therefore,as an emerging unconventional isotope,lithium has been widely used to trace various geological processes and material migration processes.In this paper,the basic characteristics of lithium isotopes in the natural system and the analytical test methods are introduced,and the practical application and theoretical principles of Li isotopes in the study of supergene and endogenetic geological processes are systematically described,in order to deepen the understanding of the isotope system,promote the application of the emerging isotopic methods in the field of Geosciences in China.
