Fragment of ancient lost continent discovered off the coast of Canada: Study

In a recent study, scientists have uncovered a splintered remnant of Earth's continental crust from millions of years ago, embedded in isolated wilderness of rrn Cana. This fragment of an ancient continent has been discovered by researchers studying rock samples on Baffin Island in Canian territory of Nunavut. 

Study

According to a study published in Journal of Petrology, team of scientists was investigating pieces of kimberlite—igneous rocks that sometimes contain diamonds—when y ticed that ir mineral signature closely matched an ancient part of Earth's crust kwn as rth Atlantic craton (NAC.) Baffin Island, located in between Canian mainland and Greenland, is a vast Arctic expanse covering over 500,000 square kilometers (almost 200,000 square miles), making it fifth-largest island in world.

While island comprises part of newest recognized territory in Cana – Nunavut, formally established in 1999 – a discovery shows this ancient landmass has undisclosed ties that stretch backward in time so far, y emanate from a distant geologic eon. While analyzing igneous rock samples recovered from diamond exploration drilling in Chidliak Kimberlite Province at sourn stretches of Baffin Island, researchers identified a mineral signature in rock y h never expected to find.

Explaining research, geologist Maya Kopylova from University of British Columbia said that Kimberlites are subterranean rockets that pick up passengers on ir way to surface and passengers are solid chunks of wall rocks that carry a wealth of details on conditions far beneath surface of our planet over time.

In this case, those passengers h completed a very long journey. team says kimberlite rocks like this, formed at depths below 150 kilometers (93 miles), are driven to surface by both geological and chemical forces. In terms of geological component, ir emergence underneath modern-day Baffin Island represents end of a colossal dispersal that occurred approximately 150 million years ago, during rifting of continental plate of rth Atlantic Craton (NAC).

To reach ir findings, team used many analytical techniques – including petrography, mineralogy, and rmobarometry – to study 120 rock samples, called xeliths, taken from kimberlite province. results showed Chidliak mantle "strikingly resembles" NAC rocks from West Greenland in terms of ir bulk composition and mineral chemistry while showing numerous contrasts with markers from or cratons.
