Global deformation of the Earth caused by large-scale continental glaciation: implications for the evolution of ice ages and the averaged thickness of the lithosphere.

Recently the phenomenon of true polar wander since the late Cretaceous has been the subject of a number of investigations since it may have a bearing on the diverse areas of mantle convection and the evolution of ice ages. Such types of polar motions can influence as well the characteristic time scale of ice ages from earlier geological epochs, such as the Silurian which took place some 400 million years ago. It is suggested that true polar wander may furnish a mechanism which could eventually terminate the ice-age cycles. This premise is explored. -from Current Antarctic Literature
