海水在等温条件下(23.5℃)经过73天的逐步蒸发,使重量达到为原来水的1/138。在蒸发作用的各个阶段,从卤水中完全提取出沉淀物,剩下的卤水作进一步蒸发。硫同位素成分的沉淀物与有关卤水表现出如下特征:原始海水的初始δ~(34)S=+20‰。沉淀物和相伴卤水的δ~(34)S值在石膏稳定区至石盐稳定区端点时均逐渐降低,两者分别降至+19.09‰(沉淀物和+18.40‰(卤水),且沉淀物的δ~(34)值总是高于卤水的δ~(34)值,但越靠近石盐稳定区
Seawater was gradually evaporated for 73 days under isothermal conditions (23.5 ° C), bringing the weight to 1/138 of the original water. At each stage of the evaporation, the precipitate is completely extracted from the brine and the remaining brine is further evaporated. Sediments of sulfur isotopes and related brine show the following characteristics: Initial δ ~ (34) S = + 20 ‰ of the original seawater. The δ ~ (34) S values of sediments and accompanying brine decreased gradually when the gypsum stabilized zone reached the end of the stable zone of rock salt, both decreased to + 19.09 ‰ (sediment and + 18.40 ‰ respectively), and the sediment The δ ~ (34) value of brine is always higher than that of brine, but the closer to the stable area of salt rock
