We analyzed the origin and evolution of the Horoman peridotite massif based on major and trace elements and Hf-Nd-Pb-Sr isotope systematics. We identified at least four events in the evolution of the Horoman peridotite. In addition, we found the least radiogenic lead from the Horoman peridotite so far. Furthermore, we have developed the Hf isotope analytical method at ng/g levels.

根据主量元素、微量元素和Hf-NdPbsr同位素体系，分析了霍罗曼橄榄岩地块的成因和演化。在霍罗曼橄榄岩的演化过程中，我们确定了至少四个事件。此外，我们还发现了迄今为止霍罗曼橄榄岩中最不具放射性成因的铅。此外，我们还发展了ng/g水平的Hf同位素分析方法。
