Abstract

The thermal conductivity of iron is now known to be much larger than had been thought, implying that thermal convection and radiogenic heating would not have been enough to sustain the Earth’s geodynamo; here it is shown that the precipitation of magnesium-bearing minerals from the core could have served as the required power source.
