Anhydrite ( CaSO 4). In nature, Gypsum and Anyhdrite occur as beds or nodular masses up to a few metres thick. Gypsum is formed by the hydration of Anhydrite. The depth of hydration can range from the surface of the deposit down to three hundred metres, depending on temperature and pressure, topography and the structure of the deposit.
