Calcite in the form of oolitic limestone from Bedford, Indiana.Oct 13, 2023 · Gypsum, common sulfate mineral of great commercial importance, composed of hydrated calcium sulfate. It occurs in extensive beds associated with other evaporite minerals, particularly in Permian and Triassic sedimentary formations; it is deposited from ocean brine, followed by anhydrite and halite. Its chemical formula, CaSO4·2H2O, indicates that each unit of gypsum is composed of one calcium (Ca) atom, one sulfur (S) atom, four oxygen (O) atoms, and two water (H2O) molecules. The two water molecules are structurally bound to the calcium sulfate, giving gypsum its characteristic hydrated form.Sulfate minerals are delicate and occur near the Earth's surface in sedimentary rocks such as limestone, gypsum rock, and rock salt.
