本文研究了新疆锡林郭勒山橄榄岩和石榴单斜辉石岩无水矿物的矿物学特征。介绍了日本东赤寺橄榄岩体。从固溶体组成范围和铁镁分配的角度讨论了石榴石、单斜辉石、斜方辉石和橄榄石之间的亚固相线平衡。得出的结论是，在较低的温度下平衡的无水矿物的质量比任何研究橄榄岩石榴石单斜辉石组合。初步估计5-600° C和7-13 Kb为平衡的物理条件。与其他产状的类似组合进行了比较，并简要讨论了地质意义。
The mineralogy of anhydrous minerals of peridotite and garnet clinopyroxenite of the Mt. Higasi-Akaisi peridotite mass, Japan, is described. The subsolidus equilibria among garnet, clinopyroxene, orthopyroxene and olivine are discussed in terms of composition range of solid solutions and of Fe-Mg partition. It is concluded that the anydrous minerals of this mass equilibrated at lower temperatures than any of well studied peridotite-garnet clinopyroxenite association. The tentative estimation gives 5–600° C and 7–13 Kb as the physical conditions of equilibration. Comparison with similar associations from other occurrences and geological implications are briefly discussed.
