Pakistan's newspaper on science, technology, engineering and innovation
The new mineral is preserved inside the diamond, allowing it to move from the depths of the earth to a place where humans can find it.
Scientists have discovered a new mineral that has never been seen before. What's more surprising is that the unearthed minerals are trapped in the diamond. As rare as a diamond: Scientists discovered this new mineral Davymite in a diamond-even rarer than the diamond itself. To call this new mineral rare is an understatement. Until now, davemaoite has never appeared.
Since the 1970s, scientists have conducted a theoretical analysis of the existence of this mineral-but now, they have evidence. According to a press release from the University of Nevada, Las Vegas, which led the discovery, this is "the first time a mineral in the lower mantle has been observed in nature." Davemaoite has a perovskite crystal structure that can only be produced under extreme pressure and high temperatures, just like the conditions found in the mantle at a depth of 660 to 900 kilometers, which is located between the crust and the core.
This is "the first time minerals in the lower mantle have been observed in nature." If a mineral moves to the upper layers of the earth, it will quickly decompose into other minerals. This is why no one has seen it before. But this time, this new mineral is preserved in a diamond, allowing it to move from the depths of the earth to a place where humans can find it. "It is the strength of the diamond that keeps the inclusions under high pressure," Oliver Tschauner, the geochemist who led the discovery, told Nature.
An unprocessed diamond: This green diamond was unearthed from a mine in Botswana decades ago, so this new mineral has been hidden from people's sight ever since. Eventually, it reached the hands of George Rossman, a mineralogist at the California Institute of Technology in Pasadena. A few years ago, Rossman and Tschauner began to observe the gem carefully, exploding it with X-rays to reveal more details about the minerals in it-including the existence of the mineral Davimorite. "The strength of the diamond keeps the inclusions under high pressure."
Tschauner named the mineral after the geologist Ho-kwang'Dave' Mao, a geologist known for his pioneering work in high-pressure geochemistry. This particular diamond may have formed 410 to 560 miles below the surface of the earth, making it an "extra-deep" diamond. According to "Popular Science" reports, the diamonds that capture mineral particles are strong enough to reach the surface intact. The Tschauner team from the University of Nevada in Las Vegas reported this discovery in the journal Science. They said that this discovery provides a unique perspective for in-depth geochemistry.
"For jewelers and buyers, the size, color, and clarity of a diamond are important, and inclusions-those black spots that bother jewelers-are a gift for us," Tschauner said in a statement. Davemaoite is mainly composed of calcium silicate. But it can collect radioisotopes and generate a lot of heat deep in the mantle (the layer between the crust and the core). According to the "Nature" report, this means that this mineral is a key part of how heat moves in the depths of the earth and affects plate tectonics.

Pakistan’s science and technology sector is still neglected; both at the government and public levels. Even in terms of development or criticism, there is no media to solve these problems. As we all know, as one of the main means for the public to pay attention to scientific and technological issues, the news media plays a vital role. For most people, the reality of science is what they experience through mass media channels. Good reports allow people to evaluate science policy issues and make rational personal choices; bad reports can mislead the public, who are increasingly influenced by science. The demand for science and technology newspapers has occurred, and the concept of the weekly (future daily) "Science and Technology Times" is also evolving.
