Geologic interpretations of the Dive 466 and 467 traverses (Fig. 3) up the transform wall bounding the main gabbro massif ~ 4 km south of its northern limit. a Dive profile with the geologic interpretation (1:1 section). Shear sense on fault indicated by the red arrows. b Plan view of the track on surface bathymetry collected during Mode 98. The combined traverses extend from below the gabbro-mantle contact near the base of the transform wall to ~ 250 m below the primary detachment fault surface. Toshi Yamazaki and Laurence Coogan diving scientists as indicated in a. Note that dikes are illustrated as perpendicular to the dive profiles, rather than their true orientation, which in most case is ~ east-west
