Fragment of lost continent discovered in Canada


By analyzing the samples, analysts identified part of the North Atlantic craton, a remnant of the Earth’s ancient continental crust that stretched from Labrador to Scotland.


An article on the University of British Columbia’s website explains that experts were studying Kimberlite rocks, which formed millions of years ago and were brought to the Earth’s surface by geological forces.


The samples from a De Beers Chidliak Kimberlite Province property in southern Baffin Island, however, have a mineral signature that corresponds to other parts of the craton.


"The mineral composition of other portions of the North Atlantic craton is so unique there was no mistaking it,” University of British Columbia geologist Maya Kopylova told the website.

Last year, scientists announced the discovery of the world's deepest land canyon thousands of feet below an Antarctic glacier.
