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。硼、氯同位素之间存在负相关关系。
Based on the discussion of the relationship between boron and chloride isotope composition and corresponding chemical parameters in salt lake of Qaidam basin, the relationship between boron and chloride isotopic compositions in salt lake brine and salt lake brine evolution was revealed. The boron isotopic composition of salt lake brine is mainly related to the composition of boron isotope and the content of Ca ion in brine supply water. The composition of chlorine isotope is controlled by the evaporation degree of brine. There is a negative correlation between boron and chlorine isotopes.
