PaleoPortal Fossil Preparation | Pyrite "Disease"

Pyrite. Commonly called fool's gold, pyrite is the Earth's most abundant sulfide mineral. Recognized for its brass-yellow color which resembles that of gold, pyrite is a source of iron and sulfur and is used for the production of sulfuric acid. Some types of pyrite contain enough microscopic gold to warrant mining them as a gold ore.

Chalcopyrite - Wikipedia

Pyrite is called "fool's gold" due to its shiny appearance fooling prospectors into thinking they had found gold. It consists of iron sulfide and its hardness is a 6 to 6.5. It is found in a variety of interesting shapes, sometimes forming natural cubes.

Pyrite: The mineral pyrite information and pictures

The first reaction in the weathering of pyrite includes the oxidation of pyrite by oxygen. Sulfur is oxidized to sulfate and ferrous iron is released. This reaction generates two moles of acidity for each mole of pyrite oxidized. 2 FeS 2 + 7 O 2 + 2 H 2 O => 2 Fe 2+ + 4 SO 4 2-+ 4 H + Pyrite + Oxygen + Water => Ferrous Iron + Sulfate + Acidity ...

Pyrite structure | crystallography | Britannica

Pyrite, a naturally occurring iron disulfide mineral. The name comes from the Greek word pyr, 'fire,' because pyrite emits sparks when struck by metal. Pyrite is called fool's gold; to the novice its color is deceptively similar to that of a gold nugget.

Pyrite | FeS2 | ChemSpider

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.
