Figure F73. Geophysical logging measurements in Hole 1149B are shown with lithologic units determined from cored intervals from Holes 1149A and 1149B. Resistivity, bulk density, and caliper dimensions each delineate three major intervals within the logged interval that are in general agreement with the lithologic units identified from core samples. P-wave velocities also identify three major intervals, but the lowermost increase in velocity is somewhat offset from the identified lithologic boundaries. Note the sudden change in logging parameters at the bottom of the drill pipe.
