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.

Pyrite Crystal: Meaning, Properties & Uses of Fool's Gold

2021-10-25  Pyrite belongs to the iron ore family, which makes it unsuitable for submersion in water for long periods of time. If you leave pyrite in water, it will begin to rust and degrade over time. It may be tempting to leave your pyrite crystal in a bath or water bottle, but doing so will only cause it to lose its shine.

Experimental Modeling of Ankerite–Pyrite Interaction

2021-11-14  Experimental modeling of ankerite–pyrite interaction was carried out on a multi-anvil high-pressure apparatus of a “split sphere” type (6.3 GPa, 1050–1550 °C, 20–60 h). At T ≤ 1250 °C, the formation of pyrrhotite, dolomite, magnesite, and metastable graphite was established. At higher temperatures, the generation of two immiscible melts (carbonate and sulfide ones), as

However, the mechanism of pyrite formation in sediments is still being debated.
