The research made by Ashwal suggests that there could be many pieces of various sizes of continents yet to be discovered. Also known as ‘Mauritia’, was left over by the breakup of Gondwana Land and spread over the Indian Ocean.
“According to the new results, this break-up did not involve a simple splitting of the ancient super-continent of Gondwana, but rather, a complex splintering took place with fragments of continental crust of variable sizes left adrift within the evolving Indian Ocean basin.”
This is not the first time a billion year old zircons have been found on this island. According to a study which was conducted in 2013 found various amounts of minerals in the beach sand. However, at the time received heavy criticism by the mainstream media, stating that the mineral could have been blown in by the wind. But Ashwal’s new study contradicts this.

“The fact that we found the ancient zircons in rock (6-million-year-old trachyte), corroborates the previous study and refutes any suggestion of wind-blown, wave-transported or pumice-rafted zircons for explaining the earlier results.”
