摘要：

The terrestrial ages of three Allan Hills meteorites are between 3 × 104 and 3 × 105 years and one is (1.54 -0.28+0.14) × 106 years old. The Antarctic ice sheet is therefore older than (1.54-0.28 +0.14) × 106 years and the meteorite accumulation process at Allan Hills probably began between 3 × 104 and 3 × 105 years ago.
