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. The terminal category of ocean basins is characterised by the greatest mean sediment thickness (4311m) and greatest percentage area of submarine fans (7.2%) of any ocean basin. And because of this, the ocean seafloor and also the ocean ridge is being eliminated.
