THE MINERAL ANHYDRITE or ANGELITE ... Anhydrite is a relatively common sedimentary mineral that forms massive rock layers. Anhydrite does not form directly, but is the result of the dewatering of the rock forming mineral Gypsum (CaSO4-2H2O).

Information on the mineral anhydrite ... Anhydrite is a rare mineral, since most existing specimens alter to the much more common mineral Gypsum (CaSO4 · 2H2O) from the addition of water. Some specimens only partly alter to Gypsum, leaving one part Anhydrite and the other part Gypsum.
