Thermal conductivity of fused silica, crystalline quartz, hurz burgites, 1herzolites and dunite is measured in a temperature range from the room temperature to about 1400℃ by a modified Kingery method. Thermal conductivity of the fused silica agreed with Birch's data in temperature range from the room temperature to 500℃. The conductivity of the crystalline quartz is found to be higher than Birch's values in α-quartz range. It is found that the conductivities in the X and C axis of the crystalline quartz are inverted at the transition point of the α- and β-quartz. The phonon part of the conductivities of rocks differs considerably for different specimens. It is confirmed that the conductivities of all the measured rocks increase with temperature at temperatures higher than 1200℃. This phenomenon indicates that radiative or excitonic effect becomes important at high temperatures.
