Pyrite | Indiana Geological & Water Survey
Pyrite is a pretty mineral (Fig. 1) common to Indiana, but it also has a dark side. It is composed of iron (Fe) and Sulfur (S) with a chemical formula of FeS2. Atoms are arranged in an isometric crystal structure (Fig. 2) that makes cubic crystals. It shows a brassy, bright metallic luster when fresh, but readily tarnishes to dull surfaces upon exposure (Fig. 3A).,,,,,
