Geoscientists have discovered huge rock formations off Greenland's southwestern coast, which they believe are remains of Earth's crust created
when the sea floor split some 3.8 billion years ago.
Though geo-chemical analysis has set the date of plate tectonics to 2.5 billion years ago, this is the first study to find physical evidence of
tectonics in Earth's oldest known rock structures in Greenland's Isua Belt. Geologists led by Harald Fumes of the University of Bergen, Norway,
studied the rocks. The discovery is believed to have pushed back the date of plate tectonics much closer to the Earth's formation.
