Figure F45. Downhole logs of uranium, potassium, thorium/potassium ratio (from the HNGS natural gamma tool), photoelectric effect (from the HLDS lithodensity tool), and magnetic susceptibility (from the GHMT tool) in Hole 1096C. A guide to interpretation is given beneath, and example A is discussed in the text. Depth adjustments have been applied to bring all logs to a common measurement position below the seafloor. Plag. = plagioclase, montm. = montmorillonite.
