Sea-floor spreading—Another rift
Abstract
A recent survey of intense east-west magnetic anomalies between the Galapagos Islands and South America revealed a relatively small area with a pattern of symmetry about an axis that resembles the pattern of the great oceanic rises. A sea-floor spreading rate of 3.2 cm/yr was indicated. The relationship of this pattern to the East Pacific rise suggests a different type of mantle convection and crustal spreading.
