  • Pyrite (Fool's Gold): It's for Collectors, Not for Fools!

    Pyrite is the most common of the sulfide minerals - a group which includes galena, sphalerite, chalcopyrite, and arsenopyrite. Ironically, despite its "fool's gold" nickname, pyrite and gold are often found together. Actually, it's easy to tell the two apart, as pyrite is much lighter in color, less dense, and harder (gold can be scratched with ...

    Pyrite is the most common sulfide in the Earth. In the presence of arsenopyrite its oxidation is delayed, and instead, the arsenopyrite increases its oxidation rate, releasing As(III) and As(V) species in the medium. DFT/plane waves calculations were performed on pyrite/arsenopyrite interface models to understand the stability, structure, and electronic properties of the interface.

    Pyrite occurs in large deposits in contact metamorphic rocks. Deposits of copper-bearing pyrite are widely distributed and often of great size. They usually occur in or near the contact of eruptive rocks with schists or slates. Pyrite weathers rapidly to hydrated iron oxide, goethite, or limonite; pseudomorphs of goethite after pyrite are common.
