文摘

Both upper and lower oceanic crust has been recognized in the mantle source of Chaihe-arershan basalts. The recycled oceanic components in the mantle of whole eastern China varied widely, both spatially and temporally. The ongoing Pacific slab subduction might trigger the heterogeneity of source components. Recycled oceanic components for continental intraplate basalts could maintain more water than components of typical OIBs.
