It occurs in hydrothermal deposits associated with sphalerite, pyrite, chalcopyrite, barite and ...Troilite has a chemical composition of FeS, while pyrrhotite's chemical composition is Fe (1-x) S. Pyrrhotite is deficient in iron because some of the iron sites in its crystal lattice are vacant (empty). That is why the iron in the formula has a subscript of 1-x. The value of "X" in the chemical formula of pyrrhotite can range between 1 and 0.17.

The chemical formula of sphalerite is (Zn,Fe)S. It is a zinc sulfide containing variable amounts of iron that substitutes for zinc in the mineral lattice.
