Physical properties
Hardness of 6-6.5 on the Mohs scale, brassy yellow to dark brown color, metallic luster, cubic crystal system with conchoidal fracture.
Formation & geological history
Formed through low-temperature hydrothermal activity and diagenesis in sedimentary environments, often replacing organic matter.
Uses & applications
Used in mineral collections, educational displays, and historically as a source of sulfur and sulfuric acid.
Geological facts
Commonly known as 'Fool's Gold' due to its superficial resemblance to real gold, it frequently forms striking botryoidal or nodular aggregates.
Field identification & locations
Identified by its brassy metallic luster, high density, and refusal to streak gold, commonly found in clay, shale, and coal beds.
