| Abstract: | The observed consistence of the composition of chondrules and the matrix in chondrites is explained by their origin as a result of chondrule-matrix splitting of the material of primitive (not layered) planets. According to the composition of chondrites, two main stages in the evolution of chondritic planets (silicate-metallic and olivine) are distinguished. Chondritic planets of the silicate-metallic stage were analogs of chondritic planets, whose layering resulted in the formation of the terrestrial planets. The iron-silicate evolution of chondritic matter is correlated with the evolution of carbon material in the following sequence: diamond ± moissanite → hydrocarbons → primitive organic compounds. |
