Giant fan-shaped subglacial basin under East Antarctica rewrites tectonic history
Researchers have identified a giant, fan-shaped subglacial basin province beneath East Antarctica, formed by distributed rotational extension that connects major basins such as Wilkes, Aurora, and the Lake Vostok region; this may reflect Gondwana breakup and indicates East Antarctica has a more dynamic tectonic history than previously thought, with possible implications for how the ice sheet responds to climate change.
