Sep 9, 2023 · 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.” Sep 12, 2023 · The shells that formed the limestone came from ancient marine animals such as brachiopods.
