An iron sulfide mineral, Pyrite is commonly found around the world in a variety of geological formations, from sedimentary deposits to hydrothermal veins, and as a constituent of metamorphic rocks. It forms in masses, stalactites, grains, globes, striated cubes or twelve-sided pentagonal dodecahedral crystals.
Pyrite can be found in sedimentary, magmatic, and metamorphic rock deposits, and also in hydrothermal vents, wherever there is sulfur and iron.
