Fig. 9

Slope of the trendlines of dry thermal conductivity as a function of temperature (see Fig. 8, equations in Additional file 2) as a function of thermal conductivity of the corresponding sample in the dry state at ambient temperature (λdry). Trendline and corresponding coefficient of determination, R2, are represented. Colors correspond to lithologies. Equation of the trendline is used to estimate thermal conductivity at a given temperature from dry conductivity of the sample
