摘要：

From seismic refraction data on the Northern Cocos Plate, it is found that the crust thickens with age. Assuming that processes of crustal formation have remained constant over at least the past 10 m. y. , the seismic data indicate that the thickening is caused by a gradual transformation of the top 2 km of the upper mantle into material having crustal-like velocities. Serpentinization is a possible mechanism.
