Hydration Of Anhydrite: Gypsum might also form from the hydration of anhydrite (CaSO₄). Anhydrite is a calcium sulfate mineral that lacks the water molecules current in gypsum. When exposed to h2o, anhydrite undergoes a hydration response, incorporating drinking water molecules into its composition and transforming into gypsum.
