Figure 176-4. Cross section along a lithospheric flow line over the wave-cut platform at Hole 735B, showing the proposed Leg 176 deepening of the hole and drilling transect (no vertical exaggeration). At the observed spreading rate of 0.8 cm/yr, the proposed 800 m offset of the holes equates to 100,000 year spreading increments. Simplified stratigraphy based on Leg 118 lithostratigraphy (Dick et al., 1991). The inferred ductile fault is based on the bathymetry which suggests the presence of such a structure. The paleo-horizontal is inferred on the basis of the rock rotation needed to explain the deviation of the observed magnetic inclination of 70° from the predicted 52° (Pariso et al., 1991).
