( Caracas, July 18. News24 ). – More than a thousand billion tons of diamonds are buried under our feet this week was announced by US researchers at the Massachusetts Institute of Technology.
These precious minerals are located deeper than ever has been a borehole, between 145 and 240 kilometers below the surface of our planet.
"We can not reach them, but even so, there are many more," said Ulrich Faul, a research scientist at the Department of Earth Sciences, Atmosphere and Planets at MIT.
Using seismic technology to analyze how sound waves cross the Earth, scientists detected the treasure in rocks called cratonic roots whose shape is similar to that of the inverted mountains located between the earth's crust and the Earth's mantle.
The Deep Earth Diamond Discovery Project was launched because scientists were confused when the sound waves significantly accelerated through the ancient cratonic roots.
" Diamonds are special in many ways. "One of its special properties is that the speed of sound across the diamond is more than twice as faster than in olivine, the dominant mineral in the rocks of the upper mantle "he explained.
