Abstract
Magnetic anomalies and the pattern of seismicity suggest that the present Chile Rise has been spreading at 2.7 cm/yr along a NNE axis. Older oceanic crust (25–55 m.y. BP) near the coast of Chile was generated at about 4.6 cm/yr. The NNW orientation of the anomalies implies either a gradual counter clockwise rotation of the crustal block north of the Chile Rise or a recent change in the spreading pattern.
