Data from a European satellite has revealed the tectonic underworld below the frozen southernmost continent.
The eastern section of Antarctica is buried beneath a thick ice sheet. Some scientists simply assumed that under that cold mass there was nothing more than a “frozen tectonic block,” a somewhat homogeneous mass that distinguished it from the mixed up geologies of other continents.
But with the help of data from a discontinued European satellite, scientists have now found that East Antarctica is in fact a graveyard of continental remnants. They have created stunning 3-D maps of the southernmost continent’s tectonic underworld and found that the ice has been concealing wreckage of an ancient supercontinent’s spectacular destruction.
