The formation of gypsum crystals occurs through a process called mineral accretion, where the dissolved minerals in water adhere to existing crystal surfaces and gradually enlarge them over time. This process is influenced by factors such as temperature, pressure, mineral concentration, and the presence of impurities.

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. Gypsum …
