| 摘 要： | δ~(37)Cl值可以用来指示盐湖演化过程中卤水的蒸发浓缩程度、可能的补给来源和控制因素,本文对腾格里沙漠地区12个代表性盐湖卤水样品开展了氯同位素组成研究.结果表明,研究区内沙漠盐湖卤水的δ~(37)Cl值变化范围为-0.10‰~1.36‰,平均值为0.55‰;其中,硫酸钠亚型卤水的δ~(37)Cl值范围为-0.10‰~1.36‰(平均值为0.56‰),硫酸镁亚型卤水的δ~(37)Cl值范围为0.14‰~0.82‰(平均值为0.48‰).对比柴达木盆地现代盐湖分析数据,发现区内沙漠盐湖的δ~(37)Cl平均值明显大于柴达木盆地盐湖的δ~(37)Cl平均值,并且,硫酸钠亚型卤水δ~(37)Cl最高,硫酸镁亚型卤水次之,氯化物型卤水最小.基于不同盐湖地下水咸化程度以及盐湖卤水中δ~(37)Cl值与Br/Cl系数关系的研究,揭示了研究区东部和东北部盐湖可能受到第三系地层咸水的补给,而其他盐湖主要受蒸发浓缩作用影响.δ~(37)Cl值分布特征则显示,腾格里沙漠地区部分盐湖在形成过程中可能受到区域构造活动诱发的第三系深部水补给及水-岩作用等多重因素的影响.
