Scientific paper

The results of Rietmeijer's (1988) comparison of the compositions of chondritic interplanetary dust particles with the composition of C1 chondrites is examined. Rietmeijer concluded that there has been a radial chemical differentiation between the two source regions in the inner and outer solar system. The assumption that the Mg/Si ratio of C1 chondrites is representative of the sun and the primitvie solar nebula is evaluated. Evidence bearing upon the Mg/Si ratios of planetary bodies in the inner solar system are reviewed. Data are included for Venus, the moon, Mars, S-type asteroids, and the eucrite parent bodies. It is found that these bodies are generally dominanted by mineralogies with Mg/Si ratios substantially higher than the C1 chondritic value. This regional Mg/Si ratio is shown to be consistent with the solar ratio, within experimental uncertainties.
