Iceland may be the last exposed remnant of a nearly Texas-size continent – called Icelandia – that sank beneath the North Atlantic Ocean about 10 million years ago, according to a new theory proposed by an international team of geophysicists and geologists.
The theory goes against long-standing ideas about the formation of Iceland and the North Atlantic, but the researchers say the theory explains both the geological features of the ocean floor and why Earth s crust beneath Iceland is so much thicker than it should be.
