Ancient diamonds - "travelers" open evolution superkontinetov

The Superdeep diamonds formed between 650 and 450 million years ago, show how continents developed and moved. The international group of researchers studied a chemical composition of the diamonds created at a depth from 300 to 700 km in crust and extracted on mines in Brazil and West Africa. Analysis opened unknown processes of evolution and movement of continents during early evolution of a difficult life on Earth. Continental lithospheric plates drift on Earth surface, forming "supercontinents" and destroying them. This process — a supercontinent cycle — regularly repeats...
