Physical properties

Formation & geological history

Formed in hydrothermal quartz veins or as secondary deposits in river beds (placer deposits). It is an elemental mineral occurring throughout geological history, often concentrated in Paleozoic or Precambrian rocks.

Uses & applications

Used in jewelry, electronics (conductivity), currency reserves, dentistry, and aerospace. It is also a highly prized mineral for collectors.

Geological facts

Gold is one of the few elements that can be found in its native, uncombined state. It is highly malleable and ductile; a single ounce can be beaten into a sheet covering 100 square feet.

Field identification & locations

Identify by its high density (feels very heavy for its size), malleability (it will dent or bend, not shatter), and persistent yellow color even in shade. Found in stream beds, gravel bars, and mountain quartz veins.
