The properties of subcontinental lithospheric mantle beneath the eastern North China Craton changed significantly in the Mesozoic- Cenozoic, but details are sketchy. In this study, we report major element and oxygen isotopic compositions of olivine phenocrysts from early Cretaceous Xiaoling basalts and olivine xenocrysts from Quaternary Kuandian basalts. The olivine phenocrysts from the Xiaoling basalts show relatively low Fo values (79~88), Mn/Fe (1. 3~1. 6) and Ca/Fe ratios (0. 2~1. 5), but relatively high CaO (greater than 0. 1%) and Ni/Mg values (0. 4~1. 2), indicating that the Xiaoling basalts were derived from a hybrid source of peridotite and pyroxenite within the lithoshperic mantle. Their δ18O (4. 77‰~5. 96‰, mean 5. 4‰) values significantly higher than those of the normal mantle value, further demonstrate the influence of cryogenic hydrothermal alteration oceanic crust melt/fluid components in the mantle source. The olivine xenocrysts from the Kuandian basalts have Fo values ranging from 88 to 92, together with high NiO (0. 3%~0. 4%) and low CaO (<0. 1%) and MnO contents (0. 1%~0. 2%), indicating the coexistence of fertile and refractory lithospheric mantle beneath the eastern North China Craton in the Quaternary. Their δ18O values (4. 58‰~5. 38‰, mean 5. 3‰) are close to the normal mantle value. Combined with previous olivine oxygen isotope data from different regions in North China Craton, we find that destruction of the North China Craton reached the peak in the Early Cretaceous, accompanied by a large number of crust- derived melts/fluids metasomatized the lithospheric mantle. Whereas the Cenozoic lithospheric mantle is juvenile and residual after destruction. We suggest that the metasomatism caused by the melts/fluids resulting from subduction and retreat- tearing of Paleo- Pacific plate played an important role in the weakening, erosion and final replacement of the lithospheric mantle beneath the North China Craton.
