Research Abstract

The cooling rate of chondrules in primitive meteorites gives important constraints on the model of primitive solar nebula. In this study, the profiles of Fe-Mg chemical zoning of olivines in primitive meteorites were measured and the cooling rate of individual chondrule was estimated by using the diffusion equation on the basis of the zoning profiles. The results of the cooling rates show a wide variation. I distributed the computer programs concerning these diffusion calculations to many investigators.
