Earth's Leaky Core

News   Apr 14, 2020 | Original story from the University of California - Davis.

 
Earth's Leaky Core

Earth's molten core may be leaking iron, according to researchers at UC Davis and Aarhus University, Denmark. The new study suggests heavier iron isotopes migrate toward lower temperatures -- and into the mantle -- while lighter iron isotopes circulate back down into the core. This effect could cause core material infiltrating the lowermost mantle to be enriched in heavy iron isotopes. Credit: L. O'Dwyer Brown, Aarhus University.
