Figure F189. Summary of downhole logging results in Hole 1256C and 1256D; caliper, total gamma ray emission, porosity, formation capture cross section, density, photoelectric effect, electrical resistivity, and straight Formation MicroScanner (FMS) and Ultrasonic Borehole Imaging (UBI) images (not oriented) are shown. Laboratory physical property measurements of the porosity and bulk density are also plotted along with the graphic lithology log based on core descriptions in Hole 1256B (see "Igneous Petrology and Geochemistry" in "Basement Formed at Superfast Spreading Rate (Holes 1256C and 1256D)").
