The terrestrial ages of three Allan Hills meteorites are between 3 × 10 4 and 3 × 10 5 years and one is (1.54 –0.28 +0.14 ) × 10 6 years old. The Antarctic ice sheet is therefore older than (1.54 –0.28 +0.14 ) × 10 6 years and the meteorite accumulation process at Allan Hills probably began between 3 × 10 4 and 3 × 10 5 years ago.
