The 43-57km lithospheric mantle could be consist of a suite of cumulates with crystalloblastic texture, cumulate texture and relic magmatic crystalline textures, such as orthopyroxenite, websterite, clinopyroxenite and olivine-pyroxenite. The lithospheric mantle of 43km to Moho discontinuity could be spinel harzbergite and minor spinel lherzolite, in which the spinel harzbergite and minor spinel lherzolite xenoliths are discoveried. The Moho in the region could be an transitional zone composed of cumulates in petrology.
