Resumen

Analysis of published data on sea floor spreading for the different oceans demonstrates a close correlation between interruptions of spreading at sea and compressive periods on land and between periods of spreading activity and periods of "no compression" of the orogenic regions. The evolution of both orogenic and oceanic areas appears to be rhythmic. The model is generalized to a dynamic model for the Earth's crust in which periods of global compression and extension follow alternately. Such a model fits better the geological evidences from orogenic regions than the present model for sea floor spreading which postulates an expansion in the mid ocean ridges and a compression along the continental margins underthrusted by oceanic crust.
