在建立了小行星区星云凝聚模型的基础上，对类地行星区中上物质（硅酸盐、氧化物、金属、硫化物等）的凝聚作用，以及凝聚物的水化作用进行了讨论，进而建立了包括小行星区在内的整个类地行星区的星云凝聚模式。根据地球核慢质量比和关于地球初期演化的研究结果；使用顽火辉石球粒陨石和Ｃ１陨石的化学成分分别做为地球形成区中类顽火辉石球粒陨石质星子和类Ｃ１陨石质星子的成分数据；假定类顽火辉石无球粒陨石质星子的成分与类顽火辉石球粒陨石质星子的硅酸盐部分成分相同，计算出原始地球可能由１．５８％的类铁陨石质星子、１３．９％的类顽火辉石无球粒陨石质星子、８２．５２％类顽火辉石球粒陨石质星子、２％的类Ｃ１陨石质星子组成。
Based on the establishment of the nebula cohesion model in the asteroid area, the coalescence of the upper and middle matter (silicate, oxide, metal, sulfide, etc.) in the terrestrial planetary zone and the hydration of the condensate are discussed. Then the nebula condensation pattern of the entire terrestrial planets including the asteroid zone has been established. Based on the slow mass ratio of the Earth and the research results on the evolution of the Earth at first, the chemical composition of enstatite chondrite and C1 meteorite are respectively used as the chromospheric meteorites and class C1 meteorites in the Earth formation area Assuming that the composition of the quasar-like pyrites in the quasar-like pyrites is the same as that of the silicate-like constituents in the quasar of the enchanted pyroxene chondrites, it is calculated that the original earth may consist of 1.58% Iron-like meteorites, 13.9% pyretic non-pelletized meteorites, 82.52% encyclopaedic meteorites, and 2% of the class C1 meteorites.
