An upper limit to the erosion of iron meteorites in space is calculated, based on the cosmic exposure age of the Grant meteorite and the measured depth variation of cosmogenic Ne/sup 2//sup 1/ in this meteorite. A value for E/sub m// sub a//sub x/ of approximately 1.1 x 10/sup -//sup 8/ cm/yr is found. A previous estimate based on the Siknote-Alin meteorite is discussed. (auth)
