The undation theory gives a synthesis of the terrestrial evolution, uniting geological, geophysical, and geochemical data into a comprehensive model. It accepts the major views of the new global tectonics (plate tectonics) and gives full attention to the geochemical evolution of the Earth (Fig. 1). In this way the undation theory strives for a complete integration of the earth sciences into the general spectrum of the sciences of nature (Table 1).

This model of terrestrial evolution has been developed more or less systematically in the course of half a century (1927-1977) by means of the prognosis-diagnosis method of verification. Available basic facts of observation have been arranged
