Modern potash salt deposits and associated brines of the Qaidam Basin, western China, demonstrate that some anomalous marine evaporites may have formed from nonmarine brines instead of seawater. Qaidam Basin brines are derived from meteoric river inflow mixed with small amounts of CaCl spring inflow similar in composition to many saline formation waters and hydrothermal brines. Evaporation of springenriched inflow yields a predicted mineral sequence including carnallite, bischofite, and tachyhydrite that is identical to several anomalous marine evaporites. Other mixtures of river and spring inflow produce the salt assemblage expected from evaporation of seawater.
中国西部柴达木盆地的现代钾盐矿床和相关卤水表明，一些异常的海相蒸发岩可能是由非海水卤水形成的，而不是海水。柴达木盆地的卤水来自于与少量 CaCl2 泉流混合的大气河流入流，其成分与许多盐化地层水和热液卤水相似。泉水富化入流的蒸发产生了一个预测的矿物序列，包括光卤石、水氯镁石和速水镁石，与几种异常的海相蒸发岩完全相同。其他河流和泉水混合的入流产生了从海水蒸发预期的盐类组合。
