A unique scientific discovery caught the attention of the academic world, in particular geology. it’s about two giant dots Found in the deepest layers planet earth.
One of the spots under Africa and the other under in The Pacific Ocean. These discoveries indicate That the Earth below us could be more changeable than supposed.
these areas, It is located at a depth of 2,900 km below the surface of the earthAbout halfway to Earth Centeris believed to be where rising plumes of hot rock called “deep mantle plumes” originate and reach the Earth’s surface.
report on it It was revealed by Prestigious magazine nature. It is reported that a group of experts has worked to reconstruct the mantle flow over the past thousand million years and determined that the patches are clustering and separating in a similar way to that Continents and giant continents.
The scientists said: “We discovered that, like continents, patches can coalesce, form ‘super points’ and disintegrate over time.”
The search they participated in Scientists From Universities in Australia, China and the UKis based on reconstructing the motions of tectonic plates that, as they push against each other, force the ocean floor between them, in a process known as subduction.
according to Scientistsa key aspect of this model is that although the spots change position and shape over time, they are still consistent with the pattern of kimberlite eruptions.
be tinctures, technically called Great Low Shear Rate Provinces (LLSVPs), when they first reach the surface, they produce giant volcanic eruptions, the kind that contributed to the extinction of the dinosaurs 65.5 million years ago. LLSVPs can last up to 3 billion years.
“The models also provide a framework for more precisely locating minerals associated with rising waters in the mantle. Specifically, constribte Rt, the discovery of diamond pushed to the surface Earthfrom depths of 120 to 150 km by kimberlite that appears to be associated with the patches.”
Similarly, magmatic sulphide deposits – considered to be a primary nickel reserve – have been shown to be associated with the phenomenon of ‘mantle plumes’.
