Physical properties
Hardness 6-6.5 on Mohs scale, brass-yellow color, metallic luster, cubic crystal system, specific gravity 5.0.
Formation & geological history
Formed in sedimentary, igneous, and metamorphic environments through hydrothermal activity and low-temperature precipitation.
Uses & applications
Used historically for ignition, currently in sulfuric acid production and as a mineral specimen for collectors.
Geological facts
Commonly known as 'Fool's Gold' due to its superficial resemblance to gold, though it forms distinct cubic crystals.
Field identification & locations
