A modified relationship between the phonon thermal conductivity and seismic parameter ? for silicate/oxide geomaterials is derived. The considerations are based on Debye's model of solids and on the seismic equation of state. This new relationship suggests that the phonon thermal conductivity values at the mantle/core boundary may be of about 11-14 W/mźK. Our result is in a sufficient agreement with independent laboratory data from the laser-heated diamond-anvil cell at very high pressures.
