Earth science: Hot metal
Carl B. Agee1
Abstract
The solubility of oxygen in molten iron increases at high temperature. Could this explain why Earth's mantle is poor in iron oxide, whereas the mantle of Mars, which formed under cooler conditions, is not?
The fate of light elements, such as oxygen, sulphur, carbon and hydrogen, during the formation of planetary cores has been hotly debated for decades. Forty years ago, Birch1 estimated that about 10% of Earth's core must be made of one or more of the light elements, to account for the density deficit seen in seismic observations when compared with a hypothetical core of pure iron metal.
