摘要
对有代表性的中国东部新生代玄武岩的Ｓｒ、Ｎｄ和Ｃｅ同位素组成进行了系统的研究，结合系统的微量元素研究结果，进一步阐明其地幔源区同位素组成的不均一性；利用Ｃｅ、Ｎｄ同位素地球化学给出的信息，探讨富集Ⅰ型（ＥＭⅠ）地幔端元的成因。
The Sr, Nd and Ce isotopic compositions as well as trace elemental concentrations of the Cenozoic basalts are carefully studied. The results demonstrate that there is mantle heterogeneity in eastern China. The genesis of enriched Ⅰ type (EM Ⅰ)-mantle domains is also discussed on the basis of the Ce and Nd isotopic characteristics.
