Scientists have said that iron from the Earth's core can seep into the mantle — Science and IT

Iron from the Earth's core can seep into the mantle for billions of years.

At the center of the Earth is a giant solid metal sphere surrounded by a layer of liquid iron and nickel that forms the planet's two deepest geological layers. However, these extremely hot metals do not always remain stable.

This was reported by IFLScience.

A 2020 study revealed an interesting hypothesis: iron isotopes can penetrate the rocky mantle of the Earth at a depth of about 2,900 km. However, extracting samples from such depths is an extremely difficult task. Therefore, scientists turned to experimental methods and geodynamic modeling to reproduce conditions similar to those prevailing in the deep layers of the planet, where the temperature exceeds 2000°C and the pressure is incredibly high.

Modeling showed that heavier iron isotopes tend to migrate into…
