Scientific paper

Thirty-one Antarctic H-chondrites from the Allan Hills have been analyzed for their noble gases. Seven of the specimens contain solar gases; 13 have a cosmic-ray exposure age around 8 Ma. Both fractions are as observed for H-chondrites from the rest of the world. Scrutiny of the data for 'paired samples' yields a minimum number of 17 independent falls, with six falls required for the 8 Ma peak of exposure age. The distribution of exposure ages as well as that of radiogenic He-4 and Ar-40 yield no evidence that H-chondrites from the Allan Hills region represent a mixture of populations that is different from that brought to moderate latitudes of the earth in more recent times.
