Interpretative cross-section of Kaiko Dive 172 (Fig. 3) on the western transform wall. Data from Arai et al. (2001). Cross bars on oxide gabbros indicate crystal-plastic deformation grades from 2.5 to 5 (porphyroclastic). An X indicates a cataclasite. Dashed lines are inferred high-angle faults or imbricate slump structures. Foliations are represented as dominantly sub-parallel, because they likely strike east-west, although based on drilling they have highly variable dips and often cross cut each other, dipping both north and south. Direct observation, however, indicates that the ultramylonite is conformable to the detachment fault footwall
