Geologists have found that a diamond sample discovered in Botswana comes from a depth of 660 kilometers and confirms the presence of a large amount of water inside the mantle.
It is extremely difficult to conduct research in the bowels of the Earth. But you can find out about what is happening hundreds of kilometers below us by indirect signs, for example, by the minerals that are carried out from there closer to the surface.
Recently, a diamond weighing one and a half carats was discovered in diamond mines in Botswana. Scientists have found that the diamond formed at a depth of about 660 kilometers, reported in the journal Nature Geoscience.
In total, the geologists examined 12 microscopic inclusions in the diamond structure in the sample, studying them using X-ray and Raman spectroscopy. This made it possible to find in them minerals from the Earth’s mantle, such as ringwoodite, ferropericlase and enstatite.
Thus, the combination of all three minerals told a lot about the circumstances of the formation of diamond and the appearance of inclusions in it. Geologists have found that the sample comes from a depth of 660 kilometers....<<<Read More>>>...
