A piece of Canada that broke off about 1.7 billion years ago has been found in Australia.
Geologists analyzed chemical signatures for very ancient sedimentary rocks in Georgetown, Queensland, that offer clues about where those rocks were when they formed.
At that time, the continents were drifting together to form a supercontinent called Nuna or Columbia. The data suggests that the Georgetown rocks broke off from Canada and collided with northern Australia around 1.6 billion years ago. It remained there even after Nuna broke apart 300 million years later.
The researchers found a geological signature that "cannot be linked with any other rocks in Australia," Adam Nordsvan, lead author of the new research, said in an email to CBC News.
Instead, it's "strikingly similar to other sedimentary rocks deposited at a similar time in North America, in particular the Wernecke Supergroup of the Yukon region and the Athabasca Basin."

Canada told Australia they can keep it, if they add a maple leaf to their flag.
GOLD!!!!
Very interesting. Geophysics is cool.
Thanks for posting.
Heh it’s been “lost” since 1993.
Send it back immediately.
Australia has a pretty restrictive immigration policy. They’ll likely want to deport it, even though the two countries share Commonwealth heritage.
There was no Canada back then. It wasn’t a piece of Canada.
A map showung that connection mentioned Nuna or Colunbia would have really added to this posting instead of all this kindergarten stuff.
That’s OK, there is part of North Africa just a few miles from where I live.
Not until they build a bridge to it.
The question will be will the aborigines be forced to speak English or French.
Oh, the things they find in Australia.
Good thing there were no Canadians on it or they would have had to learn to speak Australian.
This title shows how liberals use words to confuse and conflate more than to impart information. There is so much wrong with that head line, why should we even start to describe how wrong it is?
Liberals are even horrible when they are simply trying to describe how Pangea broke up 1.7 billion years ago.

(It's a joke boy, a funny. Nice boy, but about as sharp as a pile of vegemite.)
That’s probably why BenLurkin posted just such a helpful graphic in the topic I linked up there in #26.
