石膏水化水的同位素组成是一个敏感的诊断工具，用于指定其形成的机制，无论是从蒸发的盐水，通过水化或原位在地表水或地下水中通过氧化的硫化物。首先，石膏是在与母卤水的同位素平衡中形成的;随后，通过石膏的重结晶机制或通过水扩散到完整的晶体中，在潮湿条件下迅速发生水交换。然而，在干旱条件下，原始同位素记录在某些情况下自更新世以来一直被保存下来。
The isotopic composition of the hydration water of gypsum is a sensitive diagnostic tool for specifying the mechanisms of its formation, either from an evaporating brine, by hydration of anhydriate orin situformation in surface or groundwaters through oxidation of sulfides. Primarily, gypsum is formed in isotopic equilibrium with the mother brine; later, exchange of water occurs rapidly under humid conditions by means of a mechanism of recrystallization of gypsum or through diffusion of water into the intact crystal. Under arid conditions, however, the primary isotopic record has been preserved, in some instances, since the Pleistocene.
