摘  要:
Rb、Sr是一对亲石分散元素,由于它们独特的化学性质,在表生地球化学作用过程中,表现了特殊的地球化学行为。所以在地学研究中应用非常广泛,如矿物年龄的测定、古气候古环境的恢复、火成岩类岩石成因的研究等等。本文主要总结了以黄土沉积纪录为信息载体,利用Rb、Sr恢复古气候古环境变化信息方面的研究进展及存在问题,并提出今后在利用Rb、Sr指标再现古气候古环境的主要发展方向。

摘  要:
Rb and Sr are similar to stone in qual ity and belong to disperse elements.Because of their specific chemistry characteristics,both of them show a special geochemistry under the process of ground-earth geochemistry action.Therefore,these elements are applied widely in geology including mineral age measurement,paleoclimate and paleoenvironment restorations,and igneous rock's formation,etc.This paper,based on available materials,sums the new process of study and proposes the major studying orientations or targets in reappearance of paleoclimate and paleoenvironmen by elements of Rb and Sr in loess.
