Materials deep inside Earth have unexpected atomic properties that might force earth scientists to revise their models of Earth's internal processes. Recreating in the lab materials they believe exist in the lowermost mantle 2,900 kilometers below Earth's surface, researchers say the materials exhibit unexpected atomic properties that might influence how heat is transferred within Earth's mantle, how superplumes form, and how the magnetic field and heat generated in Earth's core travel to the planet's surface.
