Abstract: The accretion and formation processes of different type of chondrite parent body are referred to as indicators of evolution history of early solar nebula. They include pre-solar grains in primitive chondrites providing information of stellar evolution outside solar system. Mineralogic-petrologic characteristics of primitive chondrites reveal process of condensation and accretion in the early solar nebula. Oxygen isotopic composition of the major components in primitive chondrites may provide strong evidence...
