Amasia (supercontinent)

In Siberia, the boundary between the Eurasian and North/South American Plates has been stationary for millions of years.

A February 2012 study predicts Amasia will form over the North Pole, in about 50 to 200 million years, closing the Arctic Ocean.

[2] Paleogeologist Ronald Blakey has described the next 15 to 100 million years of tectonic development as fairly settled and predictable[3] but no supercontinent will form in that time frame.

Beyond that, he cautions that the geologic record is full of unexpected shifts in the tectonic activity that make further projections "very, very speculative".

[3] In addition to Amasia, two other hypothetical supercontinents—Christopher Scotese's "Pangaea Proxima" and Roy Livermore's "Novopangaea"—were illustrated in an October 2007 New Scientist article.
