Abstract. A library and laboratory research experiment was conducted in 2020 on determination and detection of mineralic and chemical appearances of mineralic gypsum in Karkar and Doodkash of Baghlan Province to determine the amount of gypsum minerals in the stones of the areas, detect the composition of gypsum stones and evaluate the importance …
The main components of gypsum are calcium sulfate (CaSO4) and water (H2O). Its chemical name is Calcium Sulphate Dihydrate and the chemical formula of gypsum is represented as CaSO4.2H2O. Gypsum and Anhydrite (CaSO4) are very similar chemically just that gypsum has 2 water molecules and Anhydrite does not contain any water molecules.
