CaSO4 . 2H2O
Anhydrite is formed from dehydrated gypsum or to make it easier to understand when water is added to anhydrite it becomes gypsum as we can see from their chemical formulas [Anhydrite (CaSO4) and Gypsum (CaSO4-2H2O)].
Gypsum is calcium sulfate - CaSO4.
CaSO4 = gypsum CaSO42H2O = Gypsum Selenite 2H2O =Selenite
Gypsum, common mineral consisting of hydrated calcium sulfate (CaSO4·2H2O).
Gypsum is a sulfate.
