http://webmineral.com/help/Diaphaneity.shtml 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.
WebPyrite is invariably present but varies from a minor component (e.g., Red Dog, Howard's Pass, and Century) to the dominant sulfide (e.g., Cirque, Meggen, and HYC). Pyrrhotite occurs in some Proterozoic deposits (Mt. Isa and Sullivan), implying more reducing and/or higher-temperature conditions.
