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.

通过研究西准噶尔达拉布特蛇绿混杂岩中方辉橄榄岩和橄榄辉石岩的岩石学特征，分析方辉橄榄岩广泛发育的铬尖晶石和斜方辉石构成的蠕虫状共生连晶结构的成因，得出结论认为：这种共生连晶结构不是前人所认为的文象结构或者石榴石的后成合晶，而是原始地幔岩熔融形成富铬岩浆的演化产物。

Following evidences indicate that lherzolite and garnet pyroxenite xenoliths in basalts are captures of mantle fragments when host magma ascending: crystallizing temperatures and pressures of cpx megacrysts and some phenocrysts in host magmas are greater than equilibrium temperatures and pressures of xenoliths; calculated REE partition pattern of assumed equilibrium melts is not comparable with that of studied host basalt rocks; olivine in xenoliths is not in equilibrium with basalt rocks.

寄主玄武岩的单斜辉石斑晶—熔体平衡温度高于石榴石二辉橄榄岩和石榴石辉石岩包体的平衡温度，单斜辉石巨晶和部分斑晶—熔体平衡压力大于包体平衡压力，寄主碱性玄武岩的稀土配分型式和所计算的与尖晶石二辉橄榄岩包体平衡的熔体的稀土配分型式不同，包体橄榄石与寄主岩浆之间的Fe-Mg交换系数低于0.30，均表明包体与寄主玄武岩浆之间不存在平衡关系，因此，包体是被寄主玄武岩浆捕虏的上地幔碎块。
