(CNN)Found-- one lost continent, concealing beneath a tropical vacation location.
It may sound implausible, however deep at the bottom of the Indian Ocean, a research study group, led by South Africa's University of the Witwatersrand , has actually discovered pieces of an ancient continent.
The lava-covered piece of continent, called 'Mauritia,' was discovered under the popular island of Mauritius.
According to the report released today in the journal Nature Communications , the piece of crust is left over from the break up of Gondwanaland, a super-continent that existed more than 200 million years earlier.
Containing rocks as much as 3.6 billion years of ages, Gondawanaland split into exactly what now are Africa, South America, Antarctica, India and Australia.
Professor Lewis Ashwal, lead author of the paper, states there are a variety of pieces of "undiscovered continent" of different sizes topped the Indian Ocean, left over by the separation.
"This break up did not include a basic splitting of the ancient super-continent of Gondwana," states Ashwal , however "a complex splintering accompanied pieces of continental crust of variable sizes left adrift within the developing Indian Ocean basin."
The group made the discovery by evaluating a mineral-- zircon-- discovered in rocks gushed up by lava throughout volcanic eruptions.
They stated that residues of the mineral were way too old to come from Mauritius. "Mauritius is an island, and there is no rock older than 9 million years of ages on the island," states Ashwal. By studying rocks on the island, they discovered zircons that were 3 billion years old.
The scientists state these findings substantiate a research study carried out in 2013 that discovered traces of ancient zircons in beach sand. Critics stated the mineral might have been blown in by the wind, or brought in by the researchers .
Ashwal states the truth the group discovered ancient zircons in rock "refutes any tip of wind-blown, pumice-rafted or wave-transported zircons."
The scientists state their outcomes show, in no unsure terms, "the presence of ancient continental crust below Mauritius."
That continent may be lost permanently, however it's still leaving traces to advise us of its presence.
"The truth that we have actually discovered zircons of this age shows that there are much older crustal products under Mauritius that might just have actually stemmed from a continent," stated Ashwal.
