In four-facies peridotite, clinopyroxene (Cpx) contains abundant information concerning partial melting and mantle metasomatism due to its low melting point. Based on detailed studies of petrographic characteristics and major elements of minerals, the authors analyzed trace elements of Cpx in the peridotitic xenoliths from Jining area, Inner Mongolia. The properties and evolution of the subcontinental lithosphere mantle (SCLM) beneath Jining area in Cenozoic period have been discussed in comparison with things of lithospheric mantle (SCLM) beneath Hebi and Shanwang areas in the North China Craton. The peridotitic xenoliths from Hebi and Shanwang areas represent samples from the Archean (relict) and Phanerozoic (new accreted) mantle, respectively. The Jining peridotitic xenoliths are dominated by spinel-lherzolites. The lherzolites have mineral assemblage of olivine (42%～72%)＋orthopyroxene (12%～50%)＋clinopyroxene (5%～20%)＋spinel (<5%). Compared with Hebi (coarse-grained) and Shanwang (fine-grained) peridotites，Jining peridotitic xenoliths mainly display the transitional porphyroclastic texture. The olivine Mg# values of Jining peridotitic xenoliths range from 89.4 to 91.4, quite consistent with the data obtained by previous researchers, and are fairly close to the values of peridotitic xenoliths from Shanwang and Yangyuan xenoliths. The samples were collected from a fertile lithospheric mantle.The Jining SCLM was formed from the relics after low partial melting of the primitive mantle. Most of the samples have a partial melting degree of 5%～10% with only a few lower than 5%. The Jining SCLM has undergone silicate melt/fluid metasomatism, quite similar to things experienced by Shanwang SCLM. The relationship between the Ol-Mg# and the equilibrium temperature of the peridotites suggests the coexistence of fertile mantle and refractory-transitional mantle beneath the study area in Cenozoic period. Such phenomena might be attributed to the reformation of the cratonic SCLM by the upwelling asthenospheric materials and the eventual replacement resulting from the cooling of the upwelled asthenosphere under heterogeneous conditions.
