: bulk thermal conductivity; : radiogenic heat production; : volumetric heat capacity of solid; : porosity; : hydraulic conductivity; impermeable refers to -40 m/d. Values were derived from [11, 18–23] with more details about the Cenozoic in Frick et al. [9] and the pre-Cenozoic in Sippel et al. [11].
