Fig. 6From: Heat flow density estimates in the Upper Rhine Graben using laboratory measurements of thermal conductivity on sedimentary rocksBox and whisker plots of thermal conductivity ranges for the various lithologies, measurements on samples in the dry state at ambient temperature. Thermal conductivity of samples in the dry state at ambient temperature as a function of porosity. Error bars are the standard deviations of thermal conductivities. The yellow polygon indicates the general trend of evolution of conductivity as a function of porosityBack to article page
