olivine rock

基本解釋

The major rock forming minerals include olivine, orthopyroxene, clinopyroxene, plagioclase and amphibole.
其主要造巖礦物為橄欖石、斜方輝石、單斜輝石、斜長(zhǎng)石和角閃石。
Ultrabasic rocks have a silica content less than 45%. Peridotite is the typical intrusive rock which consists of olivine and pyroxene.
超基性巖的SiO2含量小于45%，它的侵入巖叫做橄欖巖，主要由橄欖石、輝石等礦物組成。

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.
巖石中橄欖石和輝石的變形都是由粗變細(xì)重結(jié)晶過程，尖晶石則有較明顯的溶解、遷移和再沉淀作用。
