The eclogites are composed of garnet, phengite, epidote, quartz, rutile, etc.
榴辉岩由石榴子石、多硅白云母、绿帘石、石英、金红石等组成。

Therefore, much caution should be exercised when the Si content of phengite is used to estimate the pressure of a retrograde process.
因此，利用多硅白云母的硅含量来探讨退变质过程压力时必须加倍小心。

The low-temperature eclogites from the subduction-accretionary complex in the North Qilian Mountain occur as lenses within blueschists and phengite-schists.
