Team of Scientists Discovered a mineral never before found in diamonds Taken from The depth of the earth. He was baptized. “davemaoita“In memory of a prominent geophysicist Ho-Kwang (Dave) Mao.
According to the record Direct science, The first example of a type of mineral piedra perovskita, Formed by high pressure calcium silicate.
For a long time, davemaoite was expected to be the most abundant and geochemically important mineral in the Earth’s crust. But scientists have never found direct evidence for its existence. Why? Because As it moves to the surface it breaks down into other minerals and the pressure decreases.
However, An analysis Botswana diamond, About which the coat was formed 660 kilometers below the surface Of our planet, revealing the domavoid model trapped inside. as a consequence, The International Mineral Society has confirmed DoveMite as a new mineral.
For the first time, high-pressure calcium silicate peroxide (CaSiO3) has been identified as a naturally occurring mineral from the earth’s crust. Research and Technology Policy Aaron Celestian
“The discovery of davmavoid was amazing,” the study’s lead author told LiveScience. Oliver Shaner, Mineralogist at the University of Nevada in Las Vegas. Tschauner and his colleagues invented the Davmavoid model with a technique called synchrotron X-ray diffraction, which focuses beams of high energy rays at certain points within the diamond with microscopic precision. “By measuring the angle and intensity of the returning light, researchers can find out what is insideShaner explained. “The davmavoid pattern in the diamond was only a few micrometers (in a millionth of a meter), so less powerful sampling techniques would have missed it,” he added.
Davemaoite is believed to play an important geochemical role in the Earth’s crust. Scientists believe that the mineral too May contain other trace elements including uranium and thorium, Which releases heat through radioactive decay. Therefore, davemaoite can help The Earth’s crust generates a significant amount of heatShaner said.

In a 2014 study published in the journal Science, Scientists described another theoretical high pressure mineral from the mantle, which is known Bridge. However, the Bridgemanite model did not originate from the mantle but from the inside of a meteorite. “Davemaoite’s discovery shows that diamonds can form beneath the crust more than previously thought, and suggests that they may be the best place to search for minerals in the new mantle,” Tschauner added.
“Sonar’s work inspires confidence in discovering other difficult high-pressure phases in nature,” he said. Yingwei Fe, In a related science article by a geophysicist at the Carnegie Institution for Science in Washington. “Such a direct model of the inaccessible bottom surface would fill the gap in our knowledge of the chemical composition of the entire mantle of our planet.”.
