Five stages of the formation of the earth
Abstract
A five-stage scheme of the evolution of the earth is presented, in which the passage from one stage to the next involves a 'quantum leap' in geotectonic structure. Starting 6600 million years ago, the stages involve the formation of the core, the formation of the mantle, the formation of oceanic-type crust, the formation of ancient platforms, and consolidation (the present stage) after which there will presumably be no more earthquakes or volcanic activity.
