Gold is formed like?

Scientists at the University of Queensland (Australia) have announced that research shows that gold is produced by water and earthquakes.

The results of this study have just been published in Nature Geoscience. Dion Weatherley, a geophysicist at the University of Queensland, Australia and the lead author of the study revealed: 'Earthquakes cause geological faults, creating numerous gaps. Water quickly filled these gaps. The special thing happens in about 10km underground, where the pressure and temperature are extremely high.

"Such environmental conditions, coupled with high concentrations of carbon dioxide, silicon dioxide and some other essential substances, will help to create gold. After that, aftershocks or other earthquakes make the slots. wider openings make the pressure drop suddenly, the water quickly evaporates and any gold particles that exist in the liquid are precipitated almost immediately. '

Gold - the demand of people never runs out.

The tectonic process in the Earth's crust caused repeated earthquakes to help form sedimentary gold (sandy sediment) . Scientists say the world's gold originated from sedimentary circuits formed during the geological formations that took place 3 billion years ago.

To answer the question about the origin of gold, how can gold change from a molten state to a solid state that can be exploited? Scientists have reproduced the process of reducing pressure in gaps filled with fluids in an earthquake.

With this way, they have the answer.The molten gold from the ground has been pushed up by the movement of the Earth's crust. Gold comes in the form of ingots due to the minerals being oxidized by the weather and the washing away of dust into streams, rivers where gold accumulates or the associated water activity.

Research by Australian geologists also said that the only tremor will not produce gold of economic value. To form a circuit containing 100 tons of gold will take 100,000 years.

Discovering the mechanism of gold formation will help people in finding and exploring new gold mines in the future. People have calculated the world gold reserves to 250 thousand tons. So far, humanity has exploited about 150 thousand tons of gold from the ground. The average annual production is 2,300 tons, the gold ore will run out in 2050.

In Vietnam, gold ore is scattered in many places with small scale, the total resource is about a few thousand tons and the reserve is only a few hundred tons. Until now, nearly 500 points of ore and gold mines (actual gold ore and other gold containing ore) have been discovered. Of which, nearly 30 places were searched and evaluated for reserves of about 300 tons of gold.
