Cooling history of Earth's core with high thermal conductivity
CJ Davies - Physics of the Earth and Planetary Interiors, 2015 - Elsevier
Thermal evolution models of Earth's core constrain the power available to the geodynamo
process that generates the geomagnetic field, the evolution of the solid inner core and the
thermal history of the overlying mantle. Recent upward revision of the thermal conductivity of
liquid iron mixtures by a factor of 2–3 has drastically reduced the estimated power available
to generate the present-day geomagnetic field. Moreover, this high conductivity increases
the amount of heat that is conducted out of the core down the adiabatic gradient, bringing it …
