Origin / Origin of Gold. Gold is one of the treasures, often found in places where there have been volcanoes in the past, and comes from hot, liquid magma that is inside the earth. When magma cools down, it becomes hard and rocky. Sometimes gold is produced that can occur in various ways in the earth:
Gold dust - The name for gold in very small particles
Nuggets - Gold in nuggets, also called 'nuggets'
Gold vein - Gold that is in the ground in a long, narrow layer.
Gold veins - Rivers Seas Oceans. Gold veins often lie in places where there have been volcanoes in the past. Gold is found at the bottom of some rivers, because the water coming from the mountains carries the grains of gold. When the river water flows slowly or stands still, the gold particles sink to the bottom. There is also gold in the seas and oceans. On average, every cubic meter (1000 liters) of seawater contains about 0.03 milligrams of gold.
