Figure F25. Crossplot of Site 1192 porosity and thermal conductivity. Superimposed are the power law curves, constructed from the observed range in porosity, for ideal end-member sedimentary facies: sandstones (red/upper curve), limestones (blue/center curve), and shales (black/lower curve). The observed thermal conductivities lie between the shale and sandstone curves, suggesting that much of the sediment at Site 1192 represents primarily mixed clay/sandstone sediment facies.
