WebAnhydrite is commonly associated with calcite, halite, and sulfides such as galena, chalcopyrite, molybdenite, and pyrite in vein deposits. Anhydrite is most frequently found in evaporite deposits with gypsum by precipitation of calcium sulfate from evaporation of seawater. Anhydrite can also form through the dehydration of gypsum. botines cecilia bolocco
