Remains of a continent that was once located between India and Madagascar was discovered near the island of Mauritius.

Before the collapse of the supercontinent Gondwana less than 200 million years ago, there was a plate of a small continent between India and Madagascar, which disappeared about 84 million years ago. In an article published in the journal Nature Communications, South African paleogeologist Lewis Ashwal and his co-authors report that they have managed to find the remains of the lost continent on the modern island of Mauritius.

The crust of the Earth is composed of old and thick continental plates and comparatively young and thin plates of the ocean floor. Mauritius is a volcanic island formed by an eruption between 8 and 9 million years ago. However, scientists have found individual fragments among its rocks, dated to a much more impressive age - about 3 billion years. Moreover, it was zircon, a mineral that is characteristic of continental rocks.

Note that for the first time such ancient zircon samples were found in Mauritius a few years ago, but they were found in the local sand and could well have been brought by the sea from the nearest continent (from the island to, for example, Africa - about 2000 km). However, this time the find was made directly in the frozen rocks of the island itself. “The fact that we found zircon of the corresponding age here indicates that there are ancient rocks under Mauritius that can only be of continental origin,” emphasizes Luis Eschval.

Scientists speculate that the heavy remnants of the continental plate that sank beneath the Indian Ocean may explain a number of gravitational anomalies that are observed over it. The "Continent of Mauritius" could have disintegrated due to the movement of Madagascar away from India to Africa, closer to which it is located today. Perhaps other parts of it will be found on the Indian Ocean islands adjacent to Mauritius.
