Hero Text
A team of investigators explored the phase diagram of iron oxide up to the pressures it would encounter at Earth’s core-mantle boundary for the first time. Their goal was to discover whether ultralow-velocity zones beneath the surface could be enriched with iron oxide, accounting for their effect on seismic waves.
