Conclusion

When plate tectonics -- the reigning paradigm in the earth sciences -- was first elaborated in the 1960s, less than 0.0001% of the deep ocean had been explored and less than 20% of the land area had been mapped in meaningful detail. Even by the mid-1990s, only about 3 to 5% of the deep ocean basins had been explored in any kind of detail, and not much more than 25 to 30% of the land area could be said to be truly known. Scientific understanding of the earth's surface features is clearly still in its infancy, to say nothing of the earth's interior.
    V.V. Beloussov held that plate tectonics was a premature generalization of still very inadequate data on the structure of the ocean floor, and had proven to be far removed from geological reality. He wrote:


It is . . . quite understandable that attempts to employ this conception to explain concrete structural situations in a local rather than a global scale lead to increasingly complicated schemes in which it is suggested that local axes of spreading develop here and there, that they shift their position, die out, and reappear, that the rate of spreading alters repeatedly and often ceases altogether, and that lithospheric plates are broken up into an even greater number of secondary and tertiary plates. All these schemes are characterised by a complete absence of logic, and of patterns of any kind. The impression is given that certain rules of the game have been invented, and that the aim is to fit reality into these rules somehow or other. (Beloussov, 1980, p. 303)
    Plate tectonics certainly faces some overwhelming problems. Far from being a simple, elegant, all-embracing global theory, it is confronted with a multitude of observational anomalies, and has had to be patched up with a complex variety of ad-hoc modifications and auxiliary hypotheses. The existence of deep continental roots and the absence of a continuous, global asthenosphere to 'lubricate' plate motions, have rendered the classical model of plate movements untenable. There is no consensus on the thickness of the 'plates' and no certainty as to the forces responsible for their supposed movement. The hypotheses of large-scale continental drift, seafloor spreading and subduction, and the relative youth of the oceanic crust are contradicted by a considerable volume of data. Evidence for substantial vertical crustal movements and for significant amounts of submerged continental crust in the present-day oceans poses another major challenge to plate tectonics. Such evidence provides increasing confirmation of the periodic alternation of land and sea taught by theosophy.
