Lost Continent Discovered

·         21st February 2013: Scientists have discovered huge pieces of a continent from millions of years ago in the Indian Ocean.

According to the “National Geoscience”: scientists from England, South Africa, Norway and Germany have discovered land which is at the bottom of the Indian Ocean and has a width of 25- 30 km from 50-80 million years ago from a continent called Rodinia.
Scientists think that thisland was removed as a result of volcanic explosions which broke the land off from the main continent. Then gigantic waves caused by earth quakes sent the island to the bottom of the Indian Ocean. Scientists named this piece “Mauritia”.

Scientists say that the continents today are all detached from Rodinia and made today’s world in the last 1 billion years.

It is 2 thousand km away from Africa’s southeast, in the 115 islands of the Seychelles and the island of Maritius. While scientists were investigating the sand pieces there, they discovered that the pieces belonged to a volcanic explosion which had happened 9 million years ago.

According to the Norwegian scientists, the pieces of the sand which they took the sample from Seychelles include Zirconium. They thought the Zirconium in the sand came from another piece which had met the bottom of the Indian Ocean as a result of the volcano and the waves.

With sonar and seismic submarines, it has been proved that there was this land with a width of 25- 30 km under the Indian Ocean.
