摘　　要：基于Ti元素难熔、难迁移的地球化学特征,Ti同位素能够对太阳系早期演化过程、样品源区组成进行制约。本文详细介绍了近年来有关基于溶液进样和微区原位Ti同位素的各种分析技术,并对其优缺点进行了点评;简要介绍了本课题组在溶液进样上做出的改进和对地球样品的初步研究结果,综述了目前已有的Ti同位素应用研究进展,并对其在地球深部地质过程与表生地质过程研究中的应用前景进行了展望。Because titanium has the refractory and fluid immobile characteristics,titanium isotopes have been used to constrain the early evolution process of the solar system and the composition of source of the sample.In this paper,we have made detailed introduction of recently developed various analytical methods on the basis of solution injection and in-situ microanalysis for analyzing Ti isotopes,made brief comments on the advantages and disadvantages of all those methods, briefly introduced the improvement on the device for solution injection and presented some primary analytical results of geological samples by our research group,comprehensively reviewed the advances in the applications of Ti isotope,and finally made a prospective view on the application prospect of Ti isotopes in the researches of Earth interior and supergene geological processes.
