基本解释

The major rock forming minerals include olivine, orthopyroxene, clinopyroxene, plagioclase and amphibole.
其主要造岩矿物为橄榄石、斜方辉石、单斜辉石、斜长石和角闪石。
Ultrabasic rocks have a silica content less than 45%. Peridotite is the typical intrusive rock which consists of olivine and pyroxene.
超基性岩的SiO2含量小于45%，它的侵入岩叫做橄榄岩，主要由橄榄石、辉石等矿物组成。

The deformation of olivine and pyroxene in the rock is the recrystallized process from coarse to fine grain, the spinel has obvious dissolution, migration and reprecipitation.
岩石中橄榄石和辉石的变形都是由粗变细重结晶过程，尖晶石则有较明显的溶解、迁移和再沉淀作用。
