In the depths of the Antarctic ice cover hidden the remains of the ancient continent lost, according to a study published this week in the journal Scientific Reports.
Based on information collected by the GOCE satellite from the European Space Agency (ESA), that between 2009 and 2013 studied terrestrial gravity, Combined with seismology data, a team of researchers from Kiel University in Germany and the British Antarctic Survey have obtained 3D continental plate maps, specifically from Antarctica.
According to the authors of this work, this map will help understand how plate tectonics and the dynamics of the layers interact. These pictures "They revolutionized our ability to study lesser-known Earth continents", commented Fausto Ferraccioli, one of the study authors.
Under the eastern part of Antarctica is "an interesting mosaic of geological features that reveal fundamental similarities and differences" between the bark underneath and other continents, which joined 160 million years ago, Ferraccioli added.
Within the same framework of study, it has also been found that western Antarctica has a thinner crust than in the east, formed by ancient craters separated by younger structures, which have "family similarities" with Australia and India.
ESA noted that these findings have geological interests, not purely historical. In addition, they provide clues about how the structure of the Antarctic continent affects the behavior of the ice sheet, and how quickly they will recover from melting.
