【摘要】 对福建中—新生代玄武岩的岩石化学、地球化学特征研究表明,该地区的玄武岩化学成分、微量元素和稀土元素含量都有一定的差别。这项研究对揭示源区特征和了解中国东部沿海大陆火山岩带深部地质背景提供了重要信息。更多还原

【Abstract】 The petrochemical and geochemical feature of Cenozoic basalt shows that its chemical composition and content of trace element and REE are sharply different from those of Mesozoic basalt in Fujian Province. From that, we can trace back to the difference in their characteristics of mother magma and source areas, as well as the effect of the mantle metasomatism in their evolution. The authors strive to provide some information for getting a better understanding of the background of continental volcanic rock belt located in southeastern coast of China.更多还原
