This paper reports the investigation on the petrology of spinel harzburgite and olivine pyroxenite in the Darbut ophiolitic mélange, as well as the worm-like intergrowth texture composed of Cr-spinel and orthopyroxene wide-spreading in harzburgite. Our study shows that the observed intergrowth texture is not a graphic texture or a symplectite as assumed by previous research, instead, it is a product of the evolution of the Cr-rich magma formed after the melting of the primitive mantle.

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.
