“On Earth’s surface, where oxygen is plentiful, iron will oxidize to rust,” said University of Alberta’s Professor Thomas Stachel.

“In the Earth’s deep mantle, we should find iron in its less oxidized form, known as ferrous iron, or in its metal form.”

“But what we found was the exact opposite — the deeper we go, the more oxidized iron we found.”
