How Is Gold Formed? Origins and Process ThoughtCo

May 06, 2019Scientists believe all the gold on Earth formed in supernovae and neutron star collisions that occurred before the solar system formed. In these events, gold formed during the r-process. Gold sank to the Earth's core during the planet's formation. It's only accessible today because of asteroid bombardment. Theoretically, it's possible to form gold by the

How Is Gold Formed and Where Does it Come From?

May 18, 2015At different times in the earth’s history, hot fluids circulated through gold-bearing rocks and because of the weight and chemical properties of the gold, the gold may have been carried off to form a vein or a lode. In other instances, gold flakes and nuggets broke off and were carried away by water’s currents.

The World Gold Council states that as of the end of 2017, "there were 187,200 tonnes of stocks in existence above ground". This can be represented by a cube with an edge length of about 21 meters. At $1,349 per troy ounce, 187,200 metric tonnes of gold would have a value of $8.9 trillion. According to the United States Geological Survey in 2016, about 5,726,000,000 troy ounces (178,100 t) of gold has been produced since the beginning of civilization, of which 85% remains

Gold is a very rare substance making up only ~3 parts per billion of the Earth's outer layer (imagine 1 billion smarties in one place and only 3 of them were made of gold!). Its rarity and physical properties have made gold one of the most prized of the Earth's natural resources. When gold is found in rocks it is almost always in a pure state.
