In fact, the name of Anhydrite is derived from "An" and "Hydra" meaning "without water" in reference to its similarity to Gypsum but the fact that it lacks ...
Apr 24, 2014· Calcium Sulfate Minerals. Gypsum is the more common, hydrated form of calcium sulfate. In fact, it is the most common of all sulfate minerals. Gypsum''s chemical formula is CaSO 4. 2H 2 O. The anhydrous (without water) mineral is called Anhydrite (CaSO 4).. Gypsum and Anhydrite both occur as primary minerals in Marine deposits occur when sea water .
Gypsum has the same chemical composition as the mineral Anhydrite, but contains water in its structure, which Anhydrite lacks. Many Anhydrite specimens absorb water, transforming into the more common Gypsum. Some Gypsum specimens show evidence of this, containing growths of crumpling layers that testify to their expansion from the addition of ...
Gypsum is a sedimentary rock and a crystalline mineral. "Gypsum is a soft, white to gray, "chalky" mineral composed of calcium sulfate and water," says Raymond Anderson of Iowa''s Department of Natural Resources. Gypsum''s chemical symbol is CaSO4•2H2O. Found in many parts of the world, it can occur as crystals or as deposits in beds.
Gypsum: Satin spar, a fibrous variety of gypsum from Derbyshire, England. Specimen is approximately 4 inches (10 centimeters) across. What is Gypsum? Gypsum is an evaporite mineral most commonly found in layered sedimentary deposits in association with halite, anhydrite, sulfur, calcite, and dolomite.
Gypsum is a white mineral, CaSO 2 O (hydrous calcium sulfate), used in the manufacture of cements and plasters, especially plaster of Paris (to control the rate of setting of Portland cement), and also in some fertilizers. See calcium. Gypsum is found in both mineral and rock form.
