Outline of Final Research Achievements

We have measured electrical conductivity of iron and alloys at high pressure and temperature corresponding to the Earth's core. Results demonstrate that core thermal conductivity calculated from electrical conductivity is three times as high as traditional estimate, indicating fast core cooling. The age of the inner core should be younger than one billion years. In addition, we also found that the solidus temperature of the lowermost mantle is lower by 500 K than previously thought. Since the lowermost mantle is not extensively molten, it suggests core temperature is also low. The core should include substantial mount of hydrogen to depress its melting temperature.
