Variation of maximum temperature in a mass element at radial position r. The radius r is the final position of the mass element after compaction of the body. Solid line: model H (see Table 6) with binary chondrule mixture and sintering calculated by theory of Helle et al. (1985). Dotted line: model R (see Table 6) with binary chondrule mixture and sintering calculated by theory of Rao & Chaklader (1972). Long dashed line: model Rp (see Table 6) with restriction for maximum temperature. Short dashed line: model O (see Table 6) with one-component dust material and sintering calculated by the theory of Rao & Chaklader (1972). The horizontal dashed lines indicate the transition temperatures between different petrologic types according to McSween et al. (1988) and the solidus temperatures of the Fe, Ni-FeS complex and the chondritic silicate-mixture.
