Notes: msb = meters subbasement. Depths to the axial low-velocity zone are estimated from the relationship with spreading rate shown in Figure F3 (following Purdy et al., 1992; Carbotte et al., 1997b) for ocean crust spreading at 200 mm/y. Depth in mbsf includes the 250 m thick sediment cover at Site 1256.
