Washington (AFP) – There's a lot of bling buried in the ground.
More than a quadrillion tons of diamonds to be exact ̵
But do not expect a diamond rush. These naturally occurring valuable minerals are far deeper than any drilling expedition has ever reached, about 90 to 150 miles (145 to 240 kilometers) below the surface of our planet.
"We can not come across them, but still, there are many more diamonds there than we ever thought before," said Ulrich Faul, a scientist in MIT's Department of Earth, Atmospheric and Planetary Sciences.
"This shows that diamond is not this exotic mineral, but continues. The magnitude of things is relatively common."
Using seismic technology to analyze how sound waves pass the earth, scientists discovered the mine's treasure trove Called kratonic roots shaped like inverted mountains that extend through the crust of the earth into the mantle.
These are "the oldest and most immovable parts of the rock that lie beneath the center of most continental tectonic plates," MIT explained in a statement.
The project to uncover the deep earth diameter began onds, as scientists were surprised by observations that sound waves would accelerate significantly as they pass through the roots of ancient craters.
So they put together virtual rocks from different mineral combinations to calculate how fast sound waves are flowing through them
"Diamond is special in many ways," said Faul.
"One of its special features is that the speed of sound in diamonds is more than twice that of the dominant mineral in the upper layers of the earth, olivine."
They found that the only type of rock that could be found in the diamond Kraton's reported rates contained one to two percent of diamonds.
Scientists now believe that Earth's ancient subterranean rock contains at least 1,000 times more diamonds than previously expected
Yet, very few of these gems will find their way to the jewelry store.
Diamonds are made from carbon and are created under high pressure and extreme temperatures deep inside the earth.
They occur only through volcanic eruptions near the surface, which are rare – on the order of tens of millions of years.
