An international team of geologists suggested that the current territory of Iceland is part of a sunken continent that stretched from Greenland to Europe.
The work was published in the journal GeoScienceWorld. Until now, Iceland has been one of the mysteries for geologists, since the existing theories that it was formed from and surrounded by oceanic volcanic rock are not supported by many scientific data.
Thus, the thickness of Iceland’s crust exceeds 40 kilometers, that is, seven times the thickness of an ordinary rock of this type.
Therefore, scientists from the Geological Survey of Norway and the Laboratory of Geophysical Research of the Ocean at Brest University (France) put forward the assumption that Iceland is nothing more than the remnant of the once sunken continent or part of it. In this case, the thick crust is understandable: it is simply continental.
There is reason to believe that the territory of the sunken continent, if it really existed, occupied about 600 thousand square kilometers and even, possibly, up to one million kilometers.
If the presence of these lands on the map of the planet millions of years ago can be proved, this would mean that the supercontinent Pangea, which is believed to have ceased to exist more than 50 million years ago, in fact, did not completely disintegrate. Further research will be needed to find out. They will include the collection of zircon crystals in Iceland and beyond, as well as drilling and other work.
