| 摘 要： | 本文报道了在海南岛东部晨星石炭系地层中发育的玄武岩，并对其主量和稀土元素地球化学特征进行了初步研究，结果表明该玄武岩具高铁、强亏损N－MORB型火山岩的特点，上述特征暗示了海南岛晚古生代古洋盆存在的可能。

| Abstract: | The occurrence of basalt within Carboniferous strata in Chenxing, eastern Hainan Island,is reported in this paper. The major and rare earth element compositions show that the basalt is high-MgO and characterized by high-depleted N-MORB, which suggests the possible development of a Late Palaeozoic oceanic basin in Hainan Island. |
