Gypsum Mineral | Uses and Properties

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. Gypsum is the most common sulfate mineral.

Anhydrite Mineral | Uses and Properties

Anhydrite is also found in the cap rock of salt domes and in cavities of trap rock. Anhydrite is an anhydrous calcium sulfate with a composition of CaSO 4. It is closely related to gypsum, which has a chemical composition of CaSO 4. 2H 2 O. The worldwide abundance of gypsum greatly exceeds the abundance of anhydrite.
