Figure F60. Summary of downhole log measurements and log unit divisions, Hole U1376A. Measurements include gamma ray (Pass 1 = triple combo main pass, Pass 2 = triple combo repeat pass [note that the very high gamma values observed in the pipe for Pass 2 are due to its activation by the neutron source during Pass 1]), caliper, density (moisture and density [MAD] measurements plotted using mbsf depth scale), resistivity (IMPH = medium induction phasor-processed resistivity, IDPH = deep induction phasor-processed resistivity), neutron porosity (APLC) and MAD porosity, and P-wave velocity (velocity core = VP measured on discrete core samples [mbsf depth scale], VP = compressional wave velocity measured with downhole sonic sonde [main and repeat runs]). A summary of core recovery and stratigraphic units is provided at far right (see Fig. F10 for explanation of abbreviations and patterns).
