WebSeldom the dominant mineral present, sulfur usually occurs as an accessory mineral associated with past or present volcanic activity, or from the alteration of pyrite and other sulfide minerals deposits. However, sulfur deposits large enough to be of commercial value almost always form from the alteration of gypsum and anhydrite deposits. Pyrite is the most common of sulfide minerals and is widespread in igneous, metamorphic, and sedimentary rocks. It is a common accessory mineral in igneous rocks, where it also occasionally occurs as larger masses arising from an immiscible sulfide phase in the original magma. It is found in metamorphic rocks as a product of contact metamorphism. It also forms as a high-temperature hydrothermal mineral, though it occasionally forms at lower temperatures.
