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

包括辉石、易变辉石、石等火成岩，来自于推积性的喷发。

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，石的钠石可见于成岩早期，而钾石的钠石只发生于成岩晚期。

Ankerite microclinite, a special type of rock, is closely related to the ore-forming process of massive sulfide deposits in the East Liaoning Proterozoic rift.

铁白云石微石岩作为一种特殊岩石类型，在辽东元古宙裂谷块状矿床中与成矿关系密切。

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

石碎屑中钠石组分逐渐增多，钙石组分逐渐减少，最终形成纯钠端元的钠石。

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