Hydration Of Anhydrite: Gypsum can also type through the hydration of anhydrite (CaSO₄). Anhydrite is usually a calcium sulfate mineral that lacks the drinking water molecules present in gypsum. When exposed to water, anhydrite undergoes a hydration response, incorporating drinking water molecules into its construction and transforming into gypsum.
