Almost all magmas contain sulfide- or sulfate-bearing phases. In most natural samples the sulfur-bearing phase is a sulfide, which typically is pyrrhotite (Fe_1−xS) or pyrite (FeS₂) although chalcopyrite (CuFeS₂), pentlandite ((Fe,Ni)₉S₈), sphalerite (ZnS) or molybdenite (MoS₂) may be present as well. Sulfate minerals are rare at magmatic conditions, and anhydrite (CaSO₄) is the most common. Other magmatic SO₄-bearing minerals include the sodalite group minerals (haüyne simplified formula: (Na,Ca)_4–8(Al₆Si₆(O,S)₂₄)(SO₄,Cl)_1–2), scapolite minerals (silvialite:...
