Anhydrite is commonly associated with calcite, halite, and sulfides such as galena, chalcopyrite, molybdenite, and pyrite in vein deposits. OccurrenceHalide minerals are a group of naturally occurring inorganic compounds that are salts of the halogen acids and encompass minerals with a dominant halide anion (F −, Cl −, Br −, and I − ). Complex halide minerals can also have polyatomic anions addition to, or that include, halides.
