In a diamond extracted from the depths of the Earth, scientists have discovered the first sample of a never-before-seen mineral
Another form of CaSiO₃, known as wollastonite, is found all over the world.But the crystalline structure of deivmaoite is formed only under high pressure and at high temperatures.Such conditions exist in the Earth's mantle, the solid layer between the outer core and the crust.
The existence of this pressurized form of calcium silicate was predicted more than half a century ago.Since then, it has not yet been possible to fix it, as deivmaoiteIt is extremely sensitive to pressure changes.
This time, however, geologists were able to discover the rarest mineral by observing the scattering of X-rays from the surface of the diamond.They analyzed a sample from Botswana that formed in the mantle at a depth of about 660 km fromAs a result, the International Mineralogical Association has designated deivmaoitelike a new mineral.
Deivmaoite is thought to play an important geochemical role in the Earth's mantle.Scientists speculate that the mineral may also contain other trace elements, including uranium and thorium, which releaseIt is possible that deivmaoite contributes to the release of heat in the mantle.
