Anhydrite | Properties, Formation, Occurrence and Uses Area
Anhydrite is a mineral that belongs to the sulfate mineral group. Its name is derived from the Greek words "an" (without) and "hydros" (water), indicating its lack of water content. Anhydrite is composed of calcium sulfate (CaSO4) and is chemically very similar to another well-known sulfate mineral, gypsum (CaSO4·2H2O).

ANHYDRITE (Calcium Sulfate)
Anhydrite is a relatively common sedimentary mineral that forms massive rock layers. Anhydrite does not form directly, but is the result of the dewatering of the rock forming mineral Gypsum (CaSO4-2H2O). This loss of water produces a reduction in volume of the rock layer and can cause the formation of caverns as the rock shrinks.
