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.
