| 摘 要： | 本文对皖东郯庐断裂带东侧嘉山—来安地区广泛发育的上第三系玄武岩进行了研究。在以往工作的基础上对该区作了系统的同位素和微量元素地球化学研究；对皖东玄武岩的成因及其地幔源区性质加以探讨。为论证该区存在非均一的富集型地幔提供了地球化学证据。

| Abstract: | This paper deaIs with the Neogene belt widely developwl in Jiaslian-Laian area east of Tan-Lu Fault in EastAnhui . The author has made a systematic isotope and trace eleinant study on the beis of the former work and discussedthe origin of the bet and its mantie-source character , providing with geochemical evidence for the being of inhomoge-neous enricning mantle source in the area. |
