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。
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.
