Antarctica found traces of the lost continent

The European Space Agency has discovered traces of a lost continent that has disappeared under Antarctic ice for millions of years.

The ancient continents were found due to old data from the dead European satellite GOCE.

Scientists compiled GOCE data with seismic data to create 3D maps of the earth's lithosphere. The lithosphere consists of the crust and the molten mantle below the surface of the earth and contains mountain ranges and rocky areas, which are remains of ancient continents included in the modern.

"In Eastern Antarctica, we see an exciting mosaic of geological features that reveals fundamental similarities and differences between the earth's crust beneath Antarctica and other continents to which it was connected to 160 million years ago" – said co-author of the study Fausto Ferraccioli, scientific director of the Department of Geology and Geophysics in the British Antarctic Research.

According to scientists, since Antarctica was part of the Gondwana overpopulation, which began to break down some 130 million years ago. However, the connection between Antarctica and Australia remained 55 million years ago. Recent discoveries have been discovered of the rocky islets that are the ruins of the ancient continents and provide information on how modern the continents of Earth are structured.

The study showed that Eastern Antarctica in their bark composition resembles India and Australia.

"In order to have a more coherent picture of the cortex and the upper mantle in 3D, we combined the satellite data with seismic data to understand the interaction between the tectonic plate and its dynamic mantle dynamics," says co-author Jörg Ebbing from the University of Kiel in Germany.
