What is this diamond of extraterrestrial origin discovered by researchers in Africa?

This is a major discovery that researchers have just made in Africa. As related CNNa diamond of extraterrestrial origin was discovered on Earth. The stone, called lonsdaleite, has a higher hardness and strength than a regular diamond. This rare mineral would have arrived by means of a meteorite, specify the authors of the study published September 12 in the journal Proceedings of the National Academy of Sciences.

The celestial diamond was spotted by geologist Andy Tomkins, a professor at Monash University in Australia, while he was northwest of Australia.Africa to categorize meteorites. The gemstone was found “bent” in a space rock, said study co-author Alan Salek, a doctoral student and researcher at RMIT University in Australia. The hypothesis put forward by geologists would be that the meteorite which contained the lonsdaleite came from the mantle of a dwarf planet about 4.5 billion years old. “The dwarf planet was then catastrophically hit by an asteroid, releasing pressure and leading to the formation of these really strange diamonds,” said Alan Salek, quoted by CNN.

Three ways to train

Diamonds and lonsdaleite can form in three ways: through high pressure and high temperature over a long period of time; after a collision of a meteor; or via the release of fumes of broken graphite. The method that creates the mineral can influence its size, details Paul Asimow, professor of geology and geochemistry at the California Institute of Technology.

Beneath the Earth’s surface, billions of tons of diamonds

A major breakthrough for the industry?

Either way, for the researchers, this discovery is a tremendous step forward. “Nature has provided us with a process to try and replicate in industry. We believe that lonsdaleite could be used to make tiny, ultra-hard machine parts if we can develop an industrial process that promotes the replacement of parts by graphite preformed by lonsdaleite,” enthused Andy Tomkins, who made the discovery, in a statement.

Furthermore, the researchers hypothesized that the hexagonal structure of lonsdaleite could make it up to 58% harder than ordinary diamonds. A finding that could make space diamonds a valuable resource for industrial applications.
