Antarctic erosion history reconstructed by Terre Adélie moraine geochronology
International audience 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...
