Galena a lead sulfide PbS is heavy brittle and breaks into cubes. Sphalerite is a zinc sulfide ZnS mineral that is brownish yellowish or black. It ordinarily occurs with galena and is a major ore of zinc. The iron sulfide pyrite FeS which is also called fool’s gold is common in nearly all types of rocks.
