... data was compared. The best replication of the temperature inside the rock near the surface was achieved with a conductivity of 2.8 and 1.0 W/(m•K) for granite and soil respectively. When looking at the deeper sections, the best fit was obtained for a conductivity of 5.5 and 1.0 W/(m•K) for granite...
