Fig. 8

Evolution of thermal conductivity of samples in the dry state as a function of temperature. Error bars indicate standard deviation of thermal conductivity. Colors correspond to lithologies. Names of the samples and trendlines (see Additional file 2 for equations) are indicated. The data are represented in two separate graphs for clarity
