Figure F4. Reconstruction of Site 1256 and vicinity at 14 Ma, ~1 m.y. after formation of the site at the East Pacific Rise. Positions and plate velocities (arrows labeled in millimeters per year) are relative to the Antarctic plate, which is reasonably fixed relative to the spin axis and hotspots. Bars = reconstructed positions of mapped magnetic Anomalies 5B, 5C, and 6 (ages 15–20 Ma), circles = existing DSDP/ODP drill sites.
