Physical properties
Hardness of 2.5 on the Mohs scale, golden-yellow color, metallic luster, cubic crystal system, high density and specific gravity of 19.3.
Formation & geological history
Formed through hydrothermal vein deposition and supernova nucleosynthesis, concentrated in placer deposits by weathering and erosion.
Uses & applications
Widely used in fine jewelry, financial reserves, electronics manufacturing, and aerospace applications.
Geological facts
Gold is extremely malleable and ductile; a single ounce can be drawn into a wire 50 miles long without breaking.
Field identification & locations
Identified by its distinctive yellow metallic color, high heft/weight, and resistance to tarnish; found worldwide in quartz veins and riverbeds.
