洞穴石笋是全球气候变化研究的重要载体,石笋包裹体因其捕获了当时环境条件下的水溶液或气体而封存了古气候的原始信息,因此可以重建古温度。围绕当前石笋包裹体研究的现状,阐述了包裹体的形成机制及其在石笋中的分布特征,讨论了包裹体测温(包括稳定同位素测温法、惰性气体测温法、均一温度测温法)原理、方法和技术,分析了石笋包裹体气候学存在的问题及其发展前景。
Speleothems are the important archive of numerous paleoclimatic reconstructions.The inclusions in stalagmite are extremely abundant,and can provide more clear signal for paleo-climatic research.This paper describes the formation and distribution of the inclusions in stalagmite firstly,and then presents the recent advance in the principles,methods,techniques of fluid inclusion thermometry(such as stable isotope,noble gases,liquid-vapor homogenization).Finally,it analyzes the problems in the methods and techniques for the paleo-temperature reconstruction from stalagmite inclusions and the prospects of the future work in the field.
