Gypsum and anhydrite are the hydrated and anhydrous forms of calcium sulphate, which occur in nature as evaporate deposits in the form of nodular masses or beds up to a few metres thick. Gypsum is formed by the hydration of anhydrite at or near surface, but usually passes into anhydrite below 40 to 50 metres.
