Figure F5. Site summary diagram of downhole logging operations for Site C0020 from 1200 to 2466 m wireline depth below seafloor (WSF), showing caliper (hole diameter), natural gamma ray, spontaneous potential, laterolog resistivity (RLA) of five different depths of investigation (RLA5 = deepest), neutron porosity, photoelectric factor, density, P- and S-wave velocities and Poisson’s ratio calculated from these velocities, natural gamma ray from three different radioactive materials, a series of permeability and porosity measurements by nuclear magnetic resonance (NMR) method together with their original data (combinable magnetic resonance tool, CMR), and borehole resistivity image.
