Figure F72. Radioactive element logging measurements in Hole 1149B are shown with lithologic units determined from cored intervals from Holes 1149A and 1149B. High gamma radiation values are observed between 160 and 180 mbsf and correlate to the ash-free, dark brown pelagic clay intervals of lithologic Subunit IIB. Elevated uranium concentrations are also observed throughout the majority of the logged interval, including a significant peak at 290-300 mbsf. Note the sudden change in logging parameters at the bottom of the drill pipe.
