A suite of peridotite xenoliths from the Huinan Cenozoic basalts in Jilin Province was studied to provide constraints on the nature and evolution of subcontinental lithospheric mantle (SCLM) beneath this region using electron microprobe and LA-ICPMS. Mg# and Cr# of olivines, clinopyroxenes and spinels from the Huinan peridotite xenoliths show the SCLM beneath this region is mainly fertile mantle with minor transitional/refractory relics. Chondrite-normalized REE patterns of clinopyroxenes vary widely from LREE-depleted, through convex-upward to LREE-enriched, indicating the SCLM have undergone lower than 10% fractional partial melting from primitive mantle and later silicate melt metasomatism with only a little carbonatitic melt metasomatism overprinting. These mantle characteristics, similar with that of dominate Cenozoic mantle beneath other parts of the eastern North China, reveal the coexistence of fertile and transitional lithospheric mantle beneath this region and represent comprehensive results that newly accreted materials replace the aged lithospheric mantle through melt-rock interaction /erosion and the cooling of the upwelled asthenoshpere.
