Physical properties
Hardness: 2.5-3 (Gold) vs 6-7 (Quartz Matrix); Color: Golden yellow with brown/white matrix; Luster: Metallic; Structure: Isometric; Melting point: 1,064 C.
Formation & geological history
Formed in hydrothermal veins and magmatic deposits where hot, mineral-rich fluids circulate through crustal fractures, often associated with tectonic activity.
Uses & applications
Primary source of gold for currency, electronics, jewelry, and investment bullion.
Geological facts
Gold is one of the most non-reactive chemical elements and is the most malleable and ductile metal known.
Field identification & locations
Identified by its high density, metallic luster that doesn't tarnish, and sectility. Often found in quartz veins or placer deposits near volcanic activity.
