古盐度定量研究方法综述

Summary of quanti-fied research method on paleosalinity. PGRE,

作为古环境和古气候分析中的一个重要指标,古盐度在恢复沉积时期古地理环境和古气候中具有重要的应用。为了使研究者可以根据研究需要及具体的资料来选择定量计算古盐度的方法,该文简要介了绍微量元素法、元素比值法、同位素法等盐度定量计算方法,并分析了各种方法的优缺点及使用时应注意的问题。

As an important index of paleoenvironment and paleo-climate analysis, the paleosalinity has an important role in recovering the paleoareal environment and paleocli-mate at depositional stage. Some methods for calculating the paleosalinity quantitatively, such as the methods of microelement, elemental ratio, isotope and so on, are introduced in brief, and in the same time, merits, drawbacks and the notice points in application of every method are analyzed in this paper. The aim is that researchers may select the method of calculating paleosalinity according to the need of study and the specific data.
