(CNN) – An “elusive” crystal, hypothesized matter that plays a key role in the formation of planets, has been unexpectedly found in the world’s most unique diamond. .
Research just published in the journal Science says a particular “deep diamond” accidentally encased a small amount of davemaoite, or calcium silicate CaSiO3, with a crystalline structure called perovskite, which was previously mentioned in the book. theories for half a century.
Unlike naturally occurring forms of calcium silicate, such as glass, davemaotie can only form under special conditions deep within the planet, conversely, the distribution of this mineral also affects the amount. heat in the deep mantle and determines how to regenerate this layer of material that lies hundreds of kilometers above the surface.The team, led by geochemist Yingwei from the Carnegie Institution for Science and mineralogist Oliver Tschauner from the University of Nevada, says the diamond encased davemaoite was raised from the Earth’s by complex geological processes. about 660 km underground, and that is also the mine of the legendary davemaoite.
According to Science Alert, it was found in a diamond mine in Orapa, Botswana. Laser mass spectrometry also showed that half of the calcium in davemaoite has been replaced by other elements, mainly potassium. It is possible that this is what helped the special structure of davemaoite to be preserved during the journey through the earth, in addition to the strength of the diamond shell.
Decades ago, science theorized the existence of davemaoite, which can be abundant in the deep mantle of the Earth, where no one can touch it, and is a key component of many building planet in the universe.
Davemaoite has just been officially recognized as a new natural mineral by the Commission on New Minerals, Nomenclature and Classification, of the International Minerals Association.
