Plutonic rocks consisting of pyroxene, pigeonite and plagioclase, the source of cumulate eucrites.

包括辉石、易变辉石、和斜长石等火成岩，来自于推积性的喷发。

Cumulate plagioclase appears abruptly at the base of the F unit, which rests on an erosional disconformity .

堆积的斜长石在位于侵蚀假整合之上的F单元的基底突然出现。

The albite component increases while anorthic component decreases in detrital plagioclase.The plagioclase turned into an end - member component of albite.

斜长石碎屑中钠长石组分逐渐增多，钙长石组分逐渐减少，最终形成纯钠端元的钠长石。

Latites contain plagioclase feldspar (andesine or oligoclase) as large, single crystals (phenocrysts) in a fine-grained matrix of orthoclase feldspar and augite.

安粗岩中包含斜长石（中长石或奥长石），是在正长石和普通辉石组成的细粒基质中的大单晶体（斑晶）。

Albite and labradorite both belong to plagioclase series, but they are the two different varieties.According to the characters of inclusion and transparency, iridescent ...

晕彩钠长石和晕彩拉长石都属斜长石系列,但却是两个不同的宝石品种。

Therefore, the albitization of plagioclase is shown in the early stage of diagenesis and albitization of potash feldspar appears only in the late stage of diagenesis.

因此，斜长石的钠长石化可见于成岩早期，而钾长石的钠长石化只发生于成岩晚期。
