What is the main source of gold
There are reports of gold formation, but the general consensus is that the vast majority of gold nuggets come from primary gold deposits. Alluvial gold (deposited by water movement) i. Eluvial magic (destruction of the stone where it was formed, and not by the movement of water)
How is gold formed and where does it come from
How is gold formed in geology? Over the past hundred years, the collision of all the tectonic plates of the Earth has led to the formation of horseshoe-shaped deposits of white gold. When this water is drawn from the cracks in the music, the molten gold is transferred into the bones of the rock.
Is gold a natural source of metal
Source: Geoscience Australia. Gold, as if iron, lead, copper and tin were one metal. Gold is the only yellow metal that is completely chemically stable. It does not mix easily with other substances and therefore does not corrode or tarnish. Due to this property, the pure element gold is almost certainly found in nature.
Where is gold mostly found
Most of the gold for this comes from just three countries: China, Australia and South Africa. The next gold producers in 2016 will be the United States. All the gold discovered in this way would fit in a cube, the width of each side of which, according to experts, is 28 meters.
How is gold found in nature
In its instinctive form, it resides deep in the earth’s layers, especially where it is carried by water, melting lava, volcanic eruptions, and earthquakes. How long ago, i.e. 4.5 billion years ago, geologists found gold in the earth?

What is the biggest source of gold
About 370 tons of precious metals were mined in China in 2021. China is the largest gold producer in the world.
What are coherent sources why two independent sources Cannot act as coherent sources
Two independent sources cannot be coherent, because it is known that independent sources absolutely cannot maintain a phase shift between themselves coherently. For experimental purposes, two sources derived from virtually the same parent source will certainly agree.
