We report apatitefission-track and10Be terrestrial cosmogenic nuclide (TCN) dating of14 moraine boulders originating from inland Terre Adélie, East Antarctica. These data show coolingof the Proterozoic Terre Adélie craton at <∼120°C between 350 and 300 Ma, suggesting > 4 kmtemperate glacial erosion during the Late Palaeozoic Ice Age, followed...

The erosion history of Antarctica is fundamental to our understanding of interlinks between climate and glacier dynamics. However, because of the vast polar ice sheet covering more than 99% of Antarctica land mass, the continental surface response to glacial erosion remains largely unknown. Over the last decade the subglacial topography of...
