Figure F55. Composite of wireline logs at Site 1140 compared to the core-derived lithostratigraphy. The integrated interpretation of FMS images and standard logs enable clear identification of the displayed unit boundaries. The log-derived basement unit boundaries are given in Table T15 (see "Physical Volcanology"). SGR = total gamma-ray signature. Shading = sedimentary regions with low density, resistivity, velocity, and high porosity. Other abbreviations are defined in Figure F15.
