The evolution contains five stages which are embryonic stage, juvenile stage, mature stage, declining stage, terminal stage, mature stage, and continental collision. In this stage the movement that appears and happens kind of the same with the mature stage which are the uplift and the convergence. This resulted in the cessation of a long history of subduction in the area and the gradual conversion of this continental margin to a transform fault zone. About 60 million years ago a new rift and oceanic ridge formed between Greenland and Europe, separating them and initiating the formation of oceanic crust in the Norwegian Sea and the Eurasian basin in the eastern Arctic Ocean.
