Physical properties
Hardness is 6-6.5 on the Mohs scale, color is brass-yellow with a metallic luster, and it crystallizes in the isometric system with cubic or octahedral habits.
Formation & geological history
Forms in hydrothermal veins, sedimentary rocks, and metamorphic deposits through the precipitation of iron and sulfur under reducing conditions.
Uses & applications
Used primarily in the production of sulfur dioxide and sulfuric acid, and popularly collected as a mineral specimen.
Geological facts
Commonly known as 'Fool's Gold' due to its superficial resemblance to real gold, pyrite can actually contain trace amounts of genuine gold.
Field identification & locations
Identified by its brass-yellow color, high hardness that scratches glass, brittle tenacity, and dark greenish-black streak; found globally.
