Gypsum (CaSO 4 ·2H 2 O and CaSO 4) is usually present in marine and non-marine evaporite deposits. Moreover, it can be formed by the hydration of anhydrite, since both are calcium sulfates. Gypsum ore deposits are usually found layered with other sedimentary rocks and minerals, such as halite or limestone. Large, massive gypsum …

Gypsum is calcium sulfate (CaSO 4).Refined gypsum in the anhydrite form (no water) is 29.4 percent calcium (Ca) and 23.5 percent sulfur (S). Usually, gypsum has water associated in the molecular structure (CaSO 4 ·2H2O) and is approximately 23.3 percent Ca and 18.5 percent S (plaster of paris). Gypsum fertilizer usually has other impurities …
