A team of researchers made up of geologists from the University of California (USA) concluded, after analyzing the Earth’s inner layers, that the molten core of our planet may leak heavy iron, according to a recent study published in the journal Nature Geoscience.

The researchers suggest that a significant drop in temperature from our planet’s liquid iron core to the outer rock mantle pushes the heavier iron isotopes to the planet’s surface, while the lighter ones remain inside the core.

The boundary between the liquid iron core and the rocky mantle lies about 2,900 km below the Earth’s surface. In that transition, the temperature drops more than 1,000 degrees from the hottest core to the coldest mantle, explains the portal Science Daily.

“The results suggest that the iron in the core has been seeping into the mantle for billions of years,” said study lead author Charles Lesher.
