The core of the earth holds a huge gold reservoir, and it leaves the surface: sciences

The core of the earth is rich in gold, and it is devoted by the coat and crust, has found new research.

A new study on isotopes found in the volcanic pock and which were picked up deep below the lithosphere has shown precious metals in the earth's crust, including gold, before the long, long journey to the surface, which was convinced on the convent magma.

“When the first results came, we found that we had literally hit gold!” says Geochemist Nils Messling at Göttingen University in Germany. “Our data confirmed that the material from the core, including gold and other precious metals, penetrates into the above -mentioned coats of the earth.”

Although we can access gold in the earth's crust, there is an estimated tiny fraction of the total amount that our planet has. Like a dragon, the earth lies most of its gold: studies indicate that more than 99 percent are in their metallic core – enough to cover the entire country of the earth in golden 50 centimeters (20 inches).

It makes sense: In the formation, the heavier elements sank through the planet's interior of the Mooshy and were depressed in the differentiated core, a process known as iron disasters. Meteor bombing later delivered more gold and heavy metals in the crust.

Although we have good evidence that original helium and heavy iron isotopes emerge from the earth's core, it was unclear how much of the heavy metal that we find on the surface comes from the core and how much is from space.

However, there is a way to examine: isotopes of a precious heavy metal called Ruthenium. Isotopes are variations of the same element that have different number of neutrons.

The Isotopes of Ruthenium in the Earth core differ slightly from the surface -ruthenium. This difference was too small to really recognize, but Messling and his colleagues developed new analysis techniques that enabled them to find them out.

They used their new techniques to examine Ruthenium, which was excavated from Vulcanian rocks on the Hawaiian islands, and discovered a significantly higher amount of Ruthenium-100 than in the ambient coat. This is the Isotope of Ruthenium, which comes from the Earth Core.

This discovery suggests that all siderophilic elements – which migrated to the core when the earth had been young and melted – run out of the core. Of course, this includes ruthenium, but also elements such as palladium, rhodium, platinum – and gold.

It will not occur particularly high speed, and we can not only dig 2900 kilometers (1,800 miles) to get it. Rather, the finding tells us something new about our own planet and maybe other rocky planets.

“Our results not only show that the core of the earth is not as isolated as previously assumed,” said geochemist Matthias Willbold from the University of Göttingen.

“We can now also prove that huge volumes of overwhelmed mantle material-several hundred forty metric tons of stone in the core boundary are created and climbing the surface of the earth to form ocean islands like Hawaii.”
