陨石稳定同位素研究是探索太阳系物质起源与演化的重要窗口,也是类比认识地球早期过程的重要方法。本文以钙同位素为代表,归纳总结了陨石钙同位素质量相关分馏与核合成异常的研究进展,阐述了陨石钙同位素特征对于理解早期太阳星云演化及探究小行星早期地质过程的重要意义。尽管仍有许多尚待解决的科学问题,但随着钙同位素研究的深入,尤其是钙同位素高温分馏机理的不断完善,钙同位素在天体化学领域必定会有更广阔的应用前景。 |

Stable isotopic data of meteorites provide a new insight to explore the origin and evolution of the early solar system and the Earth.In this paper,by focusing on the calcium isotopes,we summarized the latest progress on the cosmochemistry of mass-dependent calcium isotope fractionation and mass-independent calcium isotope nucleosynthetic anomalies in meteorites,which are important to understand the evolution of the early solar system and the early geological processes of asteroids.Although many scientific issues are remained to be solved,with the further development of the calcium isotopes,especially the continuously improvement of the calcium isotope fractionation mechanism in high temperature,it is believed that calcium isotopes will have a broader and more effective application prospect in the field of cosmochemistry. |
