Pyrite and pyrrhotite are minerals known as iron sulfides. When iron sulfides are exposed to water and oxygen, a series of chemical reactions breaks down the iron sulfides and forms new minerals called sulfates. These sulfates take up more space than the original iron sulfides. As they grow, the new sulfate minerals push against the surrounding rock, …

Pyrite is easily distinguishable from real gold in that it forms isometric crystals, often cubic, while gold occurs as tiny flakes or rounded nuggets. Pyrite crystals are either cubic or the 12-sided forms called pyritohedron. Pyrite crystals that occur in a block formation are commonly found in slate and phyllite.
