The study was conducted by a team of geologists led by Lewis Ashwal from the University of the Witwatersrand in Johannesburg, South Africa and was published in the Nature Communications magazine on Tuesday.
The paper, with the wordy title – Archaean zircons in Miocene oceanic hotspot rocks establish ancient continental crust beneath Mauritius – states that grains found on the island are aged up to 3 billion years while all the rocks there are no more than 9 million years old.
“Mauritius is an island, and there is no rock older than 9 million years old on the island. However, by studying the rocks on the island, we have found zircons that are as old as 3…
