Geologists have discovered a lost continent beneath Mauritius in the Indian Ocean


An ancient lost continent is lying at the bottom of the Indian Ocean, underneath the island of Mauritius, according to a new study led by a geologist from South Africa’s University of the Witwatersrand.

“Mauritia,” what researchers have dubbed the continental fragment, likely broke off of the supercontinent Gondwana as it splintered some 200 million years ago to form the continents of Africa, India, Australia, South America, and Antarctica. The team found zircons, minerals found mostly in the granite found in continents, that were as many as 3 billion years old on the island of Mauritius which is itself only 8 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,” said Lewis Ashwal, from Wits University and lead author of the report published in Nature Communications this week.
