In the depths of the Antarctic ice sheet, the remains of old lost continents are hidden, according to a study published this week in the journal Scientific Reports.
Based on information collected by the European Space Agency ESA (ESA) GOCE, that in 2009 and 2013 the Earth's gravity was studied, In combination with seismological data, a team of scientists from the University of Kiel in Germany and the British Antarctic Survey obtained a three-dimensional map of continental plates, in particular from Antarctica.
According to the authors of the work, this map will help to understand the interaction of plate tectonics and the dynamics of the deep coat. These paintings "They are revolutionizing our ability to study a less known continent on Earth", – commented Fausto Ferraccioli, one of the authors of the study.
Under the eastern part of Antarctica is "an exciting mosaic of geological features that reveal basic similarities and differences" between the bark below and other continents that joined 160 million years ago, added Ferraccioli.
As part of the same study, it was also discovered that western Antarctica has a thinner crust than in the eastern part, formed by ancient crickets separated by younger structures that have a "family resemblance" to Australia and India.
ESA notes that these discoveries are of geological importance, not purely historical. In addition, they provide guidance on how the continental structure of Antarctica affects the behavior of the ice sheet and how quickly they will recover after melting.
