Physical properties
Hardness 2.5-3 on the Mohs scale, bright golden-yellow color, metallic luster, cubic crystal system, no cleavage, and very high specific gravity around 19.3.
Formation & geological history
Formed through hydrothermal processes where gold-bearing fluids circulate through faults and fractures in the Earth's crust, depositing the metal in quartz veins.
Uses & applications
Primary uses include jewelry, monetary backing, electronics, and investment as a precious metal.
Geological facts
Gold is extremely malleable and ductile; a single gram can be drawn into a wire one kilometer long.
Field identification & locations
Identified by its high density, softness, yellow metallic color, and lack of tarnish. Found in placer deposits in rivers and streams.
