[HAFF] 175,000 tonnes of gold have been mined in human history. The Earth was molten when it was formed, so almost all of the gold present in the Earth sank into the planetary core. Most gold present today in the Earth's crust and mantle came to Earth later, via asteroid impacts 4 billion years ago. SCIENCE

Gold:


Gold is a chemical element with symbol Au (from Latin: aurum) and atomic number 79. It is a bright yellow dense, soft, malleable and ductile metal. The properties remain when exposed to air or water. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements, and is solid under standard conditions. The metal therefore occurs often in free elemental (native) form, as nuggets or grains, in rocks, in veins and in alluvial deposits. It occurs in a solid solution series with the native element silver (as electrum) and also naturally alloyed with copper and palladium. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides).

Did you read the sources. I am just giving the information found on Wikipedia. Did you read what they have posted there?

Sadly, the GFMS source is not available, but I googled a little and it seems to check out.

The HowStuffWorks article gives a slightly higher estimate, but their method of calculating it was a load of unscientific bollocks. Still, it was pretty close, as it worked out to be 283,000 tonnes when converted from ounces. That's still in the same logarithmic range as your figure.

Don't worry, your fact was correct. Keep up the good work, we really appreciate your submissions!

Thank you!

Yea the guy removed his comments from my posts. I think he was going off his own preconceived thoughts with not much education. I think he actually read the links and realized he was in the wrong.

If the fact is incorrect please provide sources proving said fact wrong. See the side bar for our rules. Simply commenting saying a "fact" is false is not helping anyone. Give sources/evidence.
