Do you know what's in the center of the earth? Well, no one knows for sure. However, it is estimated that the core is solid and the outer layer is liquid. It has been proven that the largest composition of the core is iron and nickel. The size of this nucleus is almost that of the moon. It reaches 6000 °. And yes, there is a great dynamic in the center of our planet. We are not only spinning at enormous speed in space, but the core is also spinning. Its processes feed earthquakes, volcanoes and the movements of the continents. A study just published in Nature Geoscience found that an iron leak could occur in the Earth's core that would inject heavy isotopes into the upper layers of the mantle.
Deep inside
This exchange would take place at a depth of approximately 2,900 kilometers. It is in an area where the core has a temperature thousands of degrees higher than that of the mantle. As a result, the deepest layers of the iron mantle would be enriched with heavy iron isotopes. "If this is correct, we can better understand the core-cladding interaction," said Charles Lesher in a statement. He is a study leader and professor at the University of Aarhus, Denmark.
According to Lesher, understanding this detail is relevant to examine different processes. For example, the transfer of heat and matter from the inside. Or the seismic images of the deep cloak.
It would also explain other questions. For example, why there are usually more heavy iron isotopes in mantle rocks than in meteorites, which are formed from the primary materials of the early solar system. What if all of this is true? Lesher says: "So the core has lost iron for billions of years."
Other indications
The investigation of an iron leak in the core of the earth was carried out with computer simulations. They reproduced environments at high pressures and temperatures. In addition, we were able to conclude that materials enriched with heavy iron isotopes could reach the surface. As? The springs of the jacket create columns of material from the depths, which create hot spots and regions of volcanism.
There is evidence to support this hypothesis. For example, lava from certain hot spots in Samoa and Hawaii is actually enriched with iron. It would be a good buzzword for certain foods. "It has iron … like Hawaiian lava." It may not be that commercial … but it is true.
