中文摘要:

      通过对柴达木盆地盐湖硼，氯同位素组成和相应的水化学参数关系的讨论，揭示了盐湖卤水中硼，氯同位素组成变化与盐湖卤水演化之间的关系，盐湖卤水的硼同位素组成主要是与盐湖补给水的硼同位素组成和Ｃａ离子含量有关，氯同位素组成是受卤水的蒸发程度所控制。

英文摘要:

      The reation of boron and chlorine isotopes to the hydrochemistry of salt lake brines has been investigated. The results show that the variations of the boron and chlorine isotopic compositions are associated with the evolution of the salt lake brines.The source water and Ca concentration of the brine control the boron isotopic composition of the brines.Whereas,the chlorine isotopic composition is controlled by the extent of brine evaporation. Thus, a negative relation between boron and chlorine isotopic compositions is given.
