文摘

The Cenozoic basalts of SE China have spatially varied major element compositions. “Lid effect” can well explain the spatially varied major element compositions. Mantle metasomatism explains the incompatible element enrichment in the melt. Pb isotope ratios increase from the interior to the coast. The depleted mantle matrix hosts enriched Pb isotope compositions.
