Figure F2. Bathymetric map of the Atlantis II Fracture Zone modified from Dick et al. (1991b). Locations of Hole 735B and the conjugate site 735B' (SWIR 6) are shown. SWIR 6 is located on the counter lithospheric flow line on crust of the same age and position relative to the paleo-transform as Hole 735B. Note that the spreading rate is 1.0 cm/yr to the south and 0.6 cm/yr to the north. Active southern and northern rift valleys are at 33º40'S and 31º350'S, respectively.
