Scientists have discovered a reservoir of water three times the volume of all the oceans below the Earth’s surface, according to an international study. Water has been found between the transition zone of the upper and lower mantle of the Earth. The research team analyzed a speed diamond formed 660 meters below the Earth’s surface using techniques including Raman spectroscopy and FTIR spectrometry, ANI reported.
The study confirmed something that was long just a theory, namely that ocean water accompanies subducting slabs and thus enters the transition zone. This means that our planet’s water cycle includes the interior of the Earth.
“These mineral transformations greatly hinder rock movements in the mantle,” explains Prof. Frank Brenker of the Institute for Geosciences at Goethe University Frankfurt. For example, mantle plumes, rising columns of hot rock from the deep mantle, sometimes stop directly below the transition zone. Mass movement in the opposite direction also stops.
Says Brenker: “Subducting plates often have a hard time traversing the entire transition zone. So there is a whole graveyard of such plates in this zone under Europa.”
yes, until next time. Brenker explains: “Sediments from deep-sea sediments can be large and CO2.ususus and carbonated
Undoubtedly, the prevailing conditions would be conducive to it. amounts of vine plugs (in fact, large amounts of vine plugs) “So we knew that the boundary layer has an enormous capacity to store water,” says Brenker. “However, we didn’t know if he actually did it.”
An international study in which the Frankfurt geoscientist was involved has now provided the answer. The research team analyzed a diamond from Botswana, Africa. It was formed at a depth of 660 km, right at the interface between the transition zone and the lower mantle, where ringwoodite is the predominant mineral. Diamonds from this region are very rare, even among the rare diamonds of super-deep origin, which make up only one percent of diamonds. Analysis revealed that the stone contains numerous ringwoodite inclusions, which exhibit a high water content. In addition, the research group was able to determine the chemical composition of the stone. It was almost exactly the same as virtually all mantle rock fragments found in basalts anywhere in the world. This showed that the diamond definitely came from a normal part of the Earth’s mantle. “In this study, we have delegates to have reps that don’t dry out, but transitions to,” Bren adds, “this offers those closest to us also steps to the Verne actions of an ocean within the Earth” . The difference is that there is no ocean down there, but rather hydrated rock that, according to Brenker, would not feel wet or drip water.
