Long lost continent discovered under Indian Ocean

There`s a long lost continent that has been discovered in the Indian Ocean between Madagascar and India. The evidence comes from the beaches of Mauritius where rock fragments have been found that point to an ancient continental crust.

Nature reports:

"Evidence for the long-lost land comes from Mauritius, a volcanic island about 900 kilometres east of Madagascar. The oldest basalts on the island date to about 8.9 million years ago, says Bjørn Jamtveit, a geologist at the University of Oslo. Yet grain-by-grain analyses of beach sand that Jamtveit and his colleagues collected at two sites on the Mauritian coast revealed around 20 zircons — tiny crystals of zirconium silicate that are exceedingly resistant to erosion or chemical change — that were far older.

The zircons had crystallized within granites or other igneous rocks at least 660 million years ago, says Jamtveit. One of these zircons was at least 1.97 billion years old."

oh great, just waiting for someone to call this another Atlantis candidate
