在第四届国际地质年代学、宇宙年代学和同位素地质学会议上,约有30篇讨论陨石中同位素组成的异常和宇宙年代学的论义。近20年来,根据地球、月球、太阳和各类陨石中同位素组成的研究,证实了太阳星云经历过同位素均一化的过程,使太阳系各天体的同位素组成极其相似,因而整个太阳系是来自同一团星云物质,即太阳系的同源性。
At the Fourth International Conference on Geochronology, Geochronology and Isotope Geology, there are about 30 articles discussing the anomalies of isotope composition and cosmic chronology in meteorites. In the past 20 years, based on the study of the isotope composition of the earth, the moon, the sun and various types of meteorites, it has been confirmed that the solar nebula has undergone a process of homogenization of isotopes, which makes the isotopic compositions of various celestial bodies in the solar system extremely similar. Therefore, the entire solar system is derived from the same nebula Matter, that is, the homology of the solar system.
