The abundance and isotopic composition of argon and neon in six chondrites and an achondrite were measured. The results of previous investigations are confirmed, namely Ar/K ages from 1.3 to 4.6 billion years and exposure ages from 4 to 24 million years. It is shown that the differences of the ratios Ar/sup 3//sup 6//Ar/sup 3//sup 8/ are due mainly to small amounts of trapped primordial or atmospheric argon. Using the corrected Ar/sup 3//sup 8/ abundances, a value of 9.0 with a total spread of plus or minus 20 per cent is found for the corrected Ne/sup 2//sup 1//Ar/sup 3//sup 8/ ratios. The possibility of diffusive losses of cosmogenic rare gases is discussed. (auth)
