A scientific study published in the journal Geochemistry, Geophysics, Geosystems reveals that there are billions of tons of diamonds buried in the Earth's interior.
However, its extraction seems impossible since these precious stones are found a depth of between 150 and 300 kilometers.
According to a joint research by the Massachusetts Institute of Technology (USA) and universities in several countries, diamonds were detected in the deepest sections of the cratons, the landmasses in the lithosphere, between the crust and the mantle
An anomaly found diamonds
An anomaly allowed scientists to cross this discovery. When the researchers analyzed the sound waves that help to "scan" the Earth's interior, they observed that these waves crossed the cratons at a speed twice that expected. And it is that the sound changes speed depending on the type of rock that crosses.
Academics have created computer simulations to explain this phenomenon and have concluded that the most feasible is that the deepest sections of the cratons contain a percentage of diamonds between 1 and 2%, which makes the sound pass through them. a speed superior to that of the standard craton rock
