Effects of depth- and composition-dependent thermal conductivity and the compositional viscosity ratio on the long-term evolution of large thermochemical piles of primordial material in the lower mantle of the Earth: Insights from 2-D numerical modeling

Thermal conductivity plays an important role in the thermochemical evolution of Earth’s mantle. Recent mineral physics studies suggest that the thermal conductivity of the mantle varies with pressure and composition, and this may play an important role in the evolution of the Earth’s mantle.
