| 摘 要： | 陆相咸化湖泊水体与同矿化度的海水相比，大部分具有较高的ρ（ＳＯ４２－）．陆相咸化湖泊沉积物同海洋沉积物中的ｗ（Ｓｒ）／ｗ（Ｂａ）比值相似．ｗ（Ｓｒ）／ｗ（Ｂａ）比值在沉积物中没有碳酸岩盐存在时，可以作为古盐度标志，但作为海陆相沉积区分标志是不全面的，它不能区分海洋和陆相咸化湖泊沉积物．

| Abstract: | Being compared with the sea water of the same mineralization intensity, most of continental brackish waters show high values of w (SO 2- 4). While w (Sr)/ w (Ba) values of both continental brackish lake deposit and marine deposit are very alike. w (Sr)/ w (Ba) value can be used as a criterion of palaeosalinity without carbonate in the deposit. But when it is used as the criterion of discriminating continental deposit from the marine one, it is not correct. |
