Physical properties
Hardness of 6-6.5 on Mohs scale, pale brass-yellow color, metallic luster, isometric crystal system, indistinct cleavage, and a specific gravity of 5.0.
Formation & geological history
Forms in a wide variety of geological environments from hydrothermal veins to sedimentary rocks, at temperatures ranging from low to high.
Uses & applications
Historically used to strike fire, currently used in the production of sulfur dioxide and sulfuric acid, and popular among mineral collectors.
Geological facts
Commonly known as 'Fool's Gold' due to its superficial resemblance to gold, pyrite can actually contain trace amounts of genuine gold.
Field identification & locations
Identified by its brassy yellow color, high hardness that scratches glass, brittle tenacity, and dark greenish-black streak; found worldwide.
