   Is pyrite a dangerous mineral?

   • Pyrite, often known as fool’s gold, can be one of the most dangerous minerals. Credit: Stacie Da Ponte under CCBYSA2.0. In some ways, the sulphide mineral pyrite has the opposite problem to galena. Composed of iron and sulphur, pyrite can contaminate ground water and streams via tailings waste from mines.

   What happens if pyrite decays?

   • mineral. Because pyrite is often present deep inside a specimen the resulting crystal growth and expansion can cause the specimen to fracture (Fig. 4), crumble, and slowly shatter - sometimes catastrophically.

   Why is pyrite corrosive?

   • Importantly, as well as being corrosive the oxidation product is several times the volume of the original mineral.
