plagioclase

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

包括辉、易变辉、和斜长等火岩，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 .

堆积斜长在于侵蚀假整合之上F单元基底突然出现。

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

斜长碎屑中钠长组分逐渐增多，钙长组分逐渐减少，最终钠端元钠长。

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（中长或奥长），是在正长和普通辉组细粒基质中大单晶体（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 ...

晕彩钠长和晕彩拉长都属斜长系列,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，斜长钠长化可见于岩早期，而钾长钠长化只发生于岩晚期。
