Hydration Of Anhydrite: Gypsum may form with the hydration of anhydrite (CaSO₄). Anhydrite is often a calcium sulfate mineral that lacks the drinking water molecules existing in gypsum. When exposed to drinking water, anhydrite undergoes a hydration response, incorporating drinking water molecules into its framework and reworking into gypsum.
