| Title | Pyrite |
|---|---|
| Description | This is a 14 cm wide sample of pyrite, a pale brass-yellow mineral that is an iron sulfide, FeS2. Pyrite is sometimes called “fool's gold.” It often forms cubic crystals, visible on the right hand side of this photo, but also may be massive. The lines on the surface of the large crystal shown are growth lines - they are analagous to tree rings and show how different layers were added as the crystal grew larger. |
