This petite diamond has high water content, so scientists are beginning to create theories about the sixth underground ocean ever explored.
Over time, We now know that the core of our planet is what gives it its structure, the mantle, and the Earth’s crust. However, this system is much more complex than it seems, so there are still unexplored parts and many secrets that we still don’t understand.
Previously there were already suspicions that water could exist in the depths of the asthenosphere, although it was believed that it was not in a liquid state. However, A recent find might point to the possibility of a sixth ocean beneath the planet’s surface, Large enough to rank among the planet’s most significant water sources.
A recent study published in Nature Geoscience suggests that a sixth ocean spans the globe about 400 miles (644 km) below the surface, in a boundary layer between Earth’s upper and lower mantle. The Earth’s crust averages 5 to 25 miles (8 to 40 km) deep, while the lower and upper mantles extend about 2,900 miles; the lower surface of the lower mantle forms a boundary with Earth’s outer core.
There is growing evidence from geologists that the Earth’s mantle contains a significant amount of water in porous minerals rather than a large body of groundwater on the surface, as might be expected.
The discovery that led to these assumptions was the discovery of a later examined diamond. This was mined in Botswana and probably formed at a depth of about 400 miles or 660 kilometers associated with the transition zone. The scientists now think that the watery region continues slightly beyond the transition zone and into the planet’s lower mantle based on their examination of the ringwoodite found in diamonds and the state of that mineral.
This diamond was obtained in a region with a high amount of ringwoodite. Using FTIR spectrometry, it was possible to conclude that it has a “high water content”, in addition to determining that the chemical composition of a diamond is “almost exactly the same as that of practically all the mantle rock fragments found in basalts in Any part of the world”.
These findings show that the water cycle also affects the deep earth.. The key to this is the region from where the diamond was extracted since it was found in the transition between the lower crust of the earth and the upper mantle, which is between about 410 and 660 kilometers in surface area.
Minerals, including olivine, peridot, wadsleyite, and ringwoodite, known for having high water storage capacity, make up the majority of the composition in this area. The researchers have estimated that theoretically, Rock from the transition zone “might absorb six times the water in our oceans.” Therefore, there has been talking of the existence of a sixth ocean found in the depths of the Earth, just as Jules Verne said in his ‘Journey to the Center of the Earth.
