The word "gypsum" is derived from the Greek word "gypsos," which means "chalk" or "plaster."
Gypsum is formed through the hydration of anhydrite (CaSO4), which is a form of calcium sulfate that does not contain water. Anhydrite can be formed by the dehydration of gypsum or by the precipitation of calcium sulfate from seawater.
Over time, gypsum can be found in sedimentary rocks, such as limestone and dolomite, where it is formed as a result of the evaporation of seawater. It can also be found in hydrothermal veins and as a byproduct of volcanic activity.
