石盐中溴化物的含量对于其母质卤水的来源可以提供关键性的判据。正常海相蒸发岩中石盐含50—100ppm或更多的溴化物,而在溶液二次循环中重结晶和再沉淀的石盐,其溴化物含量为20ppm或更少,特别是当再循环水是非海相水时更是如此。
The bromide content of the stone salt can provide crucial criteria for the source of its parent brine. Normal sea-phase evaporites contain 50-100 ppm or more of bromide in the stone salt while recrystallized and reprecipitated stone salts in the second cycle of the solution have a bromide content of 20 ppm or less, especially when recycled water This is especially true when it is non-marine.
