球粒陨石中高度富集难熔亲铁元素(如Os、Ir、Re、Ru等)的颗粒,有可能是太阳星云的高温冷凝产物,从中可提取出关于太阳星云早期演化过程的有价值的信息,甚至有助于揭示超新星爆发对太阳系的形成所起的作用。然而,迄今为止,在这方面尚未有人作过系统的、定量的研究。为此,本工作的目的是在单颗微粒分析的基础上,系统测定Fe-Ni金属颗粒中的难熔亲铁元素的浓度及其相互关系。
Particles that are highly enriched in chondrites with refractory pro-iron elements (such as Os, Ir, Re, Ru, etc.) may be the high temperature condensation products of the solar nebula, from which valuable information about the early evolution of the solar nebula can be extracted Information, and even help to reveal the role of supernova explosion in the formation of the solar system. However, so far, no systematic and quantitative research has been conducted in this regard. Therefore, the purpose of this work is to systematically determine the concentration of refractory iron elements in Fe-Ni metal particles and their correlations based on single particle analysis.
