【摘要】 锂同位素在地质学、地球化学研究中有着广阔的应用前景,大陆风化过程的锂同位素地球化学研究已经成为近年来国际上研究的热点,在过去十多年发展快速,并取得一批优异研究成果。系统综述了本领域国内外近年来的主要研究思路,各研究方向的主要进展,并在此基础上提出现阶段存在的问题。主要研究方向包括流域尺度大空间范围的总体研究、风化壳剖面的精细研究以及实验室内的模拟研究,均涉及水/岩作用过程的锂同位素分馏机理研究。现有研究结果有的需要进一步论证,有的相互之间存在矛盾,还有部分结论不能自圆其说,因此还需要进一步开展深入细致的研究工作。更多还原

【Abstract】 As a useful geochemical tracer,lithium isotope has been used to study some important geological or geochemical issues;recently,the study of Li isotope has become one of the most fast developing fields in geochemistry,especially in the study of continental weathering.In this paper,the authors briefly review the different domains of lithium isotope geochemical research for continental weathering process and the main achievements in each direction.Major research fields are the research of lithium isotopic geochemistry in riverine erosion system,in weathering profile system,and in laboratory experiments,Some results of the above three fields conflict from each other,so it is necessary to research more systematically and more strictly.Finally,the authors pointed out some blind sides in lithium isotope geochemical research nowadays.更多还原
