Physical properties
Hardness: 6-6.5 on Mohs scale. Color: Pale brass-yellow. Luster: Metallic. Crystal Structure: Isometric (cubic). Cleavage: Poor. Specific Gravity: 4.8-5.0.
Formation & geological history
Formed in hydrothermal veins, sedimentary rocks, and metamorphic deposits under high pressure and temperature conditions, often dating from various geological eras.
Uses & applications
Used historically for producing sulfur and sulfuric acid, in early firearms (matchlock ignition), and widely collected as a mineral specimen.
Geological facts
Commonly known as 'Fool's Gold' due to its bright metallic yellow color which often fooled inexperienced prospectors.
Field identification & locations
Identified by its brassy yellow color, high density, cubic crystal habit, and dark green-black streak. Found worldwide in association with other metallic ores.
