Hydration Of Anhydrite: Gypsum might also sort from the hydration of anhydrite (CaSO₄). Anhydrite is actually a calcium sulfate mineral that lacks the h2o molecules existing in gypsum. When exposed to h2o, anhydrite undergoes a hydration reaction, incorporating water molecules into its framework and remodeling into gypsum.
