石榴辉石岩的寄主岩是尖晶石橄榄岩类，包括尖晶石方辉橄榄岩和尖晶石二辉橄榄岩。
The host rocks of the garnet pyroxenite are spinel peridotites, including spinel harzburgite and lherzolite.
上地幔由超镁铁质的二辉橄榄岩组成，在尖晶石二辉橄榄岩和石榴石二辉橄榄岩之间有一过渡层。
The upper mantle consists of lherzolite, and it seems that there is a transition zone between spinel and garnet lherzolites.
后者以二辉石岩为代表，具典型堆积结构，与本区尖晶石二辉橄榄岩相比，具有较高的稀土元素丰度。
The latter is representive of pyroxenite, which displays the accumulate texture and has higher REE abundance than the Sp-lherzolite from the region.
