文摘

The Vietnam basalts have Sr–Nd–Hf–Pb isotopic compositions defining a DMM-EM2 array. The Nd and Hf isotopic compositions are coupled and plot along the mantle–crust array. The enriched mantle component is likely to reside in the sub-lithosphere. They may be produced by the Hainan plume from recycled eclogitic oceanic crust.
