Gypsum | Properties, Formation, Uses and Deposits
Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate (CaSO4·2H2O). It is commonly found in sedimentary rock formations and is often associated with other minerals such as anhydrite, halite, and sulfur. The name "gypsum" is derived from the Greek word "gypsos," which means "plaster" or "chalk.".
