Lost Continent Lurks Under African Island

3-Billion-Year-Old 'Lost Continent' Lurking Under African Island

It's official: A 3-billion-year-old "lost continent" lurks beneath the Indian Ocean island of Mauritius, new research confirms.

Sparkly, iridescent flecks of rocks known as zircons from Mauritius date back billions of years, to one of the earliest periods in Earth's history, the researchers found. Other rocks on the island, by contrast, are no more than 9 million years old. "The fact that we have found zircons of this age proves that there are much older crustal materials under Mauritius that could only have originated from a continent," Lewis Ashwal, lead author of the new study and a geologist at the University of the Witwatersrand, Johannesburg in South Africa, said in a statement.

Gondwana was long-lasting. Detrital zircons from Gondwana itself seems about right. Inheritance, ya know? God knows there is enough ancient material there. I zapped some 2.7 Ga zircons from one of the Gondwana continents a little while back. Once I get back inside a paywall I'll try to find the paper.

Oops. It's available online now. Ah. Between Madagascar and Southern India - particularly the Dharwar. That'll get you those ages, certainly.

That's...really cool, actually. I like that we've found such old rock. I'm sure we'll get all kinds of other discoveries from it :)

How do you fit a whole continent under an island?

Like that, give or take. Presently like this:
