Geologists have discovered recently proof of the North Atlantic Craton. Their finding represents a long-lost continent on the northeastern territory of Canada. The North Atlantic Craton was once part of an area from modern-day Scotland to Labrador.
The old continent made many parts of the Earth’s continental crust before such information could no longer be found in the annals of time.
A group of geologists from Canada discovered the long-lost continent after examining some samples of diamond rocks from the Baffin Island. They studied the kimberlite rocks that have appeared millions of years ago at approximately 140 to 400 kilometers underneath the ground.
Kimberlite could be found to the surface due to a combination of chemical and geological processes. And more significantly, they sometimes carry diamonds within them. Kimberlites have also been dubbed as subterranean rockets that deliver “passengers” on their way up. Those so-called “passengers” represent a solid bunch of wall rocks.

Kimberlites also transport lots of vital info about the underneath conditions of our planet over time. The rocks are so intriguing because they have an odd mineral composition. The North Atlantic craton stones matched a similar unique structure.
The way geologists tied all the pieces together was effortless. The old cratons in Northern Canada, Ontario, Quebec, and Nunavut display some of an essential mineralogies.
In geology, cratons are estimated to be approximately billion-year-old fragments of Earth’s continental crust. Professor Maya Kopylova, a geologist from the University of British Columbia, explained: “With these samples, we’re able to reconstruct the shapes of ancient continents based on deeper, mantle rocks.”
Approximately 175 million years ago, Earth’s continents were all connected into an only landmass, dubbed Pangea. The super-continent itself resurfaced nearly 335 million years ago when smaller continents joined.
