The water evaporated and left the mineral. Gypsum is composed of calcium sulfate (CaSO4) and water (H2O), i.e. Calcium Sulphate Dihydrate (CaSO4.2H2O). In Europe, the principal Gypsum quarries are located in Germany, UK, France, Spain, Italy, Poland, Russia and the Ukraine.ypsum is composed of calcium sulfate (CaSO4) and water (H2O), i.e. Calcium Sulphate Dihydrate (CaSO4.2H2O).
