Rocks from a lost continent that broke up around 150 million years have been accidentaly discovered deep beneath Baffin Island in northern Canada.
The rocks belong to an ancient part of Earth’s continental crust called the North Atlantic craton (NAC).
The remarkable discovery was made entirely by accident when a team of scientists rummaged through a bunch of kimberlite rock samples that had been collected from the Chidliak Kimberlite Province by a diamond exploration company.
In a new article, geologists reveal how the samples they examined displayed a mineral structure that is only seen in rocks belonging to an ancient part of Earth’s continental crust called the North Atlantic craton (NAC).
Portions of this craton have been found across a vast area stretching from Scotland to eastern Canada, via southern Greenland.
Until now, however, no remnants of the NAC had been discovered as far north as Baffin Island. The study authors were therefore extremely surprised to find such striking similarities between their kimberlite samples and the NAC.
What are cratons?
Cratons are highly stable sections of the lithosphere that are billions of years old, and which modern continental plates formed around.
While some cratons remain intact at the center of existing continents, the NAC has long since split into fragments.
The mineral composition of the North Atlantic craton is so unique there is no mistaking it.
Implications for ancient landmass
The discovery of fragments of the NAC in Baffin Island has major implications for our understanding of this ancient landmass.
- It indicates it was some 10 percent larger than previously believed.
- This is the first time that fragments of the planet’s continental plates have been retrieved from such immense depth.
With these samples, we’re able to reconstruct the shapes of ancient continents based on deeper, mantle rocks. We can now understand and map not only the uppermost skinny layer of Earth that makes up 1 percent of the planet’s volume, but our knowledge is literally and symbolically deeper.
Another ancient continent was found in Europe in September 2019. But it seems that they are being destroyed by radioactivity. More geology news on Strange Sounds and Steve Quayle. [EPSL, UBC]
150 MILLION YEARS AGO….OMG! CAN IT BE TRUE! WOW WHAT A FIND!!!BUT ON THE OTHER HAND who F@#$%ing CARES???
Are YOU KIDDDING?
agree.. 150million my small butt..
but no matter. we cant do anything with it anymore. our cycle soon will be over. and the people in the underground bunkers/cities won’t care, because they will think that it’s their own sociality. nothing new under the sun.
TheRealMLordandGod is not anyone I would believe or trust, I’ve seen enough of her videos to know nothing she does is original too much of it is incorrect.
HAVE any of you ever been to a circus,OR watched a DOG AND PONY SHOW,because thats all I see now days,one dog and pony show after another,ITS getting old,lies,after lies and layer after layer of lies…DO ANY OF YOU HAVE the power to tell when their pulling your string….
