Ross Mitchell ’07 Predicts A Future Supercontinent

8 February 2012

Geologists at Yale University have proposed a new theory to describe the formation of supercontinents, the epic process by which Earth’s major continental blocks combine into a single vast landmass. The new model radically challenges the dominant theories of how supercontinents might take shape.

In a paper published Feb. 9 in the journal Nature, Yale researchers introduce a process called orthoversion, in which each succeeding supercontinent forms 90 degrees from the geographic center of its ancient predecessor. Under the theory, the present-day Arctic Ocean and Caribbean Sea will vanish as North and South America fuse during a mutual northward migration that leads to a collision with Europe and Asia.

“After those water bodies close, we’re on our way to the next supercontinent,” said Ross N. Mitchell, the Yale doctoral student who is the paper’s first author. “You’d have the Americas meeting Eurasia practically at the North Pole.”
