Physical properties
Hardness of 2.5-3 on the Mohs scale, bright golden-yellow color with a metallic luster, cubic crystal system rarely seen as distinct crystals, hackly fracture with no cleavage, and an extremely high specific gravity of 19.3.
Formation & geological history
Formed through hydrothermal processes where gold-bearing fluids precipitate within quartz veins, or concentrated in placer deposits through weathering and erosion of primary veins.
Uses & applications
Primarily used for monetary backing, fine jewelry, investment assets, electronics manufacturing, and aerospace applications due to its malleability and corrosion resistance.
Geological facts
Gold is so malleable a single ounce can be beaten into a sheet covering 300 square feet. It does not tarnish or corrode when exposed to air or water.
Field identification & locations
Easily identified by its high density, softness, and refusal to react with acids; commonly found in stream beds and alluvial gravels worldwide.
