How Is Gypsum Formed? | Hunker

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.

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 (CaSO 4. 2H 2 O) is very similar to Anhydrite (CaSO 4).The chemical difference is that gypsum contains two waters and anhydrite is without water.

Carbonates, Evaporites, and Accessory Minerals

Gypsum is the most common evaporite mineral occurring in soils. Its occurrence and behavior is similar to that of calcite, but it is significantly more soluble; hence, it is generally found in more arid environments than calcite. It can be inherited from gypsiverous parent materials or formed as a secondary mineral.
