Some precious metals on Earth originated from the universe

A group of US and Canadian scientists have published research results that reinforce the hypothesis that some precious metals in the Earth's crust, including platinum and palladium, originate from the universe.

Geologist James Brenan, of the University of Toronto (Canada) and colleague William McDonough of the University of Maryland (USA) have recreated an environment with temperatures of up to 2,000 degrees Celsius and great pressure. At such temperatures, all metals were completely melted and separated from the Earth's rock crust.

Researchers believe that the extreme temperature in the Earth's core layer formed more than 4 billion years ago certainly melted and completely separated precious metals from the stone crust, then precious metals. This settles down in the Earth's core.

However, the fact that humans still detect, even exploit many precious metals such as osmium, iridium, platinum, ruthenium, rhodium, palladium . in the Earth's crust proves that there is a complement of metals. that on the surface of the Earth through meteor showers from the universe.

According to two researchers, meteorites that have fallen to Earth have contributed to the creation of mineral deposits on our planet.

According to astronomers' survey, in the galaxy contains huge treasures that are unexpected, which are many mines of gold, silver, platinum . and other rare metals.

So far, scientists and astronomers have found a total of more than 30,000 meteorites, of which 7,000 meteorites have been studied in detail and in most of these meteorites contain a significant amount of resources. and rare and precious minerals such as platinum, ruby, titanium, diamond .
