摘要
Five stages can be recognized with respeet to the evolution of the Jilin meteorite in the light of preliminary results available: (1) The stage of birth, fractionation and condensation of the solar nebula disc; (2) Formation of the parent body and thermal metamorphism; (3) Cooling of parent body and breaking up by impact; (4) Formation and orbiting of the Jilin meteor; (5) The falling of the meteor and the emergence of the meteorite shower. The process and characteristics are discussed at some length for each of these stages,
