Figure 171B-2. Porosity (derived from density) and resistivity showing evidence for hydrofractures in decollement zone at Site 948 of the Northern Barbados Ridge. Note that the large spikes in porosity that are interpreted as hydrofractures are also apparent in the raw LWD density data in Figure 1. The sharp drops in resistivity correlating with increases in porosity support the presence of fluidized sediment in thin intervals.
