Recycling on Earth for more than 3 billion years

Plate tectonics much older than previously thoughtOnly 100 years ago Alfred Wegener developed the theory of continental drift. However, the associated recycling process of crustal material began much earlier than previously thought. An international team of scientists with the participation of the GEOMAR Helmholtz Centre for Ocean Research Kiel and Kiel University now presented evidence that this process started more than three billion years ago. The study was published in the international journal Nature.
