Pause in geologic activity of the earth important for continent formation

A thorough analysis of geological data and freshly collected rocks indicate a pause in volcanic activity during a 100 million year period, between 2.3 and 2.2 billion years ago. This may have been at origin of continent formation, when huge amounts of lava cooled down and rose above sea level. Following this period of rest, volcanic activity came back to life again and “modern” tectonic drift, with continents fusing and breaking, started to form the continents as we know them today.
