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 has the same chemical formula as the rarer mineral Marcasite, but it crystallizes in a different crystal system, thereby classifying it as a separate mineral species. Aggregates of iron sulfide (FeS 2) where the crystal structure cannot be determined without complex analyzing material may be wrongly labeled by dealers. Some Pyrite specimens are labeled as Marcasite, and some Marcasite

Mar 17, 2019 The formation of pyrite starts with chlorite iron deposits within the ground. These compounds were formed after igneous rocks are pressurized, heated, and subsequently changed over millions of years. These chlorite compounds contain the iron found in pyrite, but they also contain silicone and oxygen, which must be removed and replaced with sulfur.
