According to a recent study on a seismic anomaly, there might be over a quadrillion tons of diamonds deposits in the Earth’s interior. The research has been recently published by the MIT researchers who were helped by scientists from the University of California at Santa Barbara, the Institut de Physique du Globe de Paris, the University of California at Berkeley, Ecole Polytechnique, the Carnegie Institution of Washington, Harvard University, the University of Science and Technology of China, the University of Bayreuth, the University of Melbourne, and University College London.
As reported by the researchers, large diamonds deposits are present at about 100 miles beneath the surface of our planet, in the very depths of the Earth’s interior.
According to the study’s report, the diamonds caches are present within cratonic roots which are the most ancient rocks that reside below the centers of the Earth’s tectonic plaques.
Diamond deposits found in the Earth’s interior after the detection of a seismic anomaly
“This shows that diamond is not perhaps this exotic mineral, but on the geological scale of things, it’s relatively common. We can’t get at them, but still, there is much more diamond there than we have ever thought before,” explained Ulrich Faul, a scientist from the MIT.
Ulrich Faul and his co-workers reached to the before-mentioned results after exploring a baffling seismic anomaly. As the researchers said, sound waves travel throughout the Earth when there form earthquakes, tsunamis, explosions, and so on.
But, when studying the Earth’s interior, the scientists faced something very puzzling. Namely, the sound waves were traveling faster than expected through the cratonic roots. Then, the international science team managed to calculate the differences in the speed of sound waves as they passed through different combinations of rocks and minerals.
Accordingly, the scientists found that the sound waves velocities when passing through the cratonic roots were similar to those of the sound waves that passed through a mixture of rocks and up to 2% diamonds.
The scientists concluded that there are massive diamonds deposits in the Earth’s interior.
