Pyrite+(Fool's+Gold)

It's chemical formula is FeS2. Pyrite is a very common mineral, found in a wide variety of geological formations from sedimentary deposits to hydrothermal veins and as a constituent of metamorphic rocks. The brassy-yellow metallic colour of pyrite has in many cases lead to people mistaking it for [|Gold], hence the common nickname 'Fool's gold'. One can tell the difference between the two easily by the strictness of pyrite's cleavage plain as it relates to golds near lack of one. Pyrite will form with shear planes and angular edges. Gold will meld onto whatever rock surrounds it. Pyrite is quite easy to distinguish from gold: pyrite is much lighter, but harder than gold and cannot be scratched with a fingernail or pocket knife. It is sometimes incorrectly recognized as Marcasite when it is mixed with silver, but Marcasite and Pyrite and two different things. it is an extremely popular mineral ans can be found almost everywhree in the world.
 * Basic Information**

Pure pyrite is made from iron and sulfur. Pyrite is commonly found to contain minor nickel, and forms a series with [|Vaesite] ; [|Bravoite] is a nickeloan variety of pyrite. It usually contains minor cobalt too, and forms a series with [|Cattierite]. Many pyrites contain minor As, see [|Arsenian Pyrite]. Pb-bearing pyrite has been described by Cabral et al. (2011). It can also contain traces of other metals, including gold.

 * How to distinguish it from similar minerals:**

Chalcopyrite is brighter yellow with a greenish hue when wet and is softer (3.5–4 on Mohs' scale). Arsenopyrite is silver white and does not become more yellow when wet.
