A large amount of mantle xenolith was found in the Cenozoic basalt in Huinan, Jilin Province, which is located in the northeastern margin of North China Craton. Main type of mantle xenoliths is spinel lherzolite. Mineral chemical compositions show the equilibrium temperature within a range of 982~1 085 ℃. According to the study of olivine and peridotite anisotropy and the mineral compositions in the peridotite, orthopyroxene can reduce the anisotropy of the bulk rock. Different kinds of rheological parameters and fabrics characteristics not only provide basic information and restrictions for further study of the upper mantle but also indicate mantle heterogeneity and the replacement (chemical erosion) may be the main dynamic mechanism of destruction in this area.
