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

包括辉、易变辉、和斜等火成岩，来自于推积性喷发。

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

堆积斜在位于侵蚀假整合之上F基底突然出现。

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

粗岩包含斜（或奥），是在正和普通辉组成细粒基质大晶体（斑晶）。

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

斜碎屑钠组分逐渐增多，钙组分逐渐减少，最终形成纯钠端钠。

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

晕彩钠和晕彩拉都属斜系列,但却是两个不同宝品种。

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，斜钠化可见于成岩早期，而钾钠化只发生于成岩晚期。
