Physical properties
Hardness of 6-6.5 on the Mohs scale, brassy yellow color, metallic luster, and cubic crystal system with conchoidal fracture.
Formation & geological history
Formed in hydrothermal veins, sedimentary rocks, and metamorphic deposits through the precipitation of iron and sulfur under reducing conditions.
Uses & applications
Used primarily in the extraction of sulfur and sulfuric acid, historical fire-starting, and as a popular mineral specimen for collectors.
Geological facts
Commonly known as 'Fool's Gold' due to its superficial resemblance to actual gold, pyrite can also contain trace amounts of gold and arsenic.
Field identification & locations
Easily identified by its pale brass-yellow color, high specific gravity, and cubic or pyritohedral crystal habits. Found worldwide, notably in Spain, Peru, and the USA.
