Gypsum depositional environment.
The definition of the depositional environment of gypsum based on the geochemistry (δ 18 O and δD) of the crystallization water could also be affected. This is because the crack-and-seal mechanism may introduce new variable aliquots of water due to the syntaxial growth of gypsum during burial and exhumation.
