Table 5 Temperature dependence of thermal conductivity

Rock type	Thermal conductivity (Wm⁻¹ K⁻¹)
Granite	\(K\left( T \right) = {1 \mathord{\left/ {\vphantom {1 {\left( {C + d \times \left( {273.15 + T} \right)} \right)}}} \right. \kern-\nulldelimiterspace} {\left( {C + d \times \left( {273.15 + T} \right)} \right)}}\)	c = 0.24094 d = 4.6019 × 10^–4
Gabbro	\(K\left( T \right) = {1 \mathord{\left/ {\vphantom {1 {\left( {C + d \times \left( {273.15 + T} \right)} \right)}}} \right. \kern-\nulldelimiterspace} {\left( {C + d \times \left( {273.15 + T} \right)} \right)}}\)	C = 0.33727 d = 3.5002 × 10^–4
Other Bedrock	\(K\left( T \right) = {{K\left( 0 \right)} \mathord{\left/ {\vphantom {{K\left( 0 \right)} {\left( {1 + b \times \left( {T - 20} \right)} \right)}}} \right. \kern-\nulldelimiterspace} {\left( {1 + b \times \left( {T - 20} \right)} \right)}}\)	b = 0.0005

Based on Miao et al. (2014) for granite and gabbro. Based on Funnell et al. (1996), K(0) indicates thermal conductivity at room temperature for other rocks
