Mineralogy and Geochemistry of Pyrite and Arsenopyrite ...

2019-4-16  Au in arsenopyrite occurs as cationic Au in solid solution, whereas Au in pyrite is in solid solution and metal nanoparticles (Au 0). The texture characteristics and trace element geochemistry among cores, transition zones, and rims of pyrites demonstrate that there are at least four pulses of fluid participating in the generation of pyrite in the deposit.

Pyrite: The mineral pyrite information and pictures

Pyrite was once used as a source of sulfur, but is now only a minor ore for both sulfur and iron. Pyrite from some localities is auriferous, and therefore is used as an ore of gold in gold-bearing localities.Pyrite was polished by the Native Americans in the early times and used as mirrors. Today, it is used as an ornamental stone, as well as a very popular stone for amateur collectors.
