#### DISCOVERING FOSSILS What is pyrite?

The mineral pyrite, or iron pyrite, is iron disulfide, FeS2. It has isometric crystals that appear as cubes or pyritohedrons (twelve irregular, pentagonal or five-sided faces). Pyrite takes its name from the Greek word 'pyros' meaning 'fire' because sparks flew from it when hit with another mineral or a metal.

#### Pyrite For Sale - FossilEra

Pyrite, FeS2, can form in a variety of different geologic environments, though these environments must contain sulfur and iron. In sedimentary rock, pyrite is typically formed in oxygen-lacking environments as a byproduct of the decay process of organic matter.
