latite

The study of petrology, mineralogy and geochemistry suggests that augite latite and augite monzonite are cognate, belonging to the upper and root parts of the volcanic dome respectively.

岩、矿物地球化学的研究表明，安岩二长岩同源，分别为火山穹窿的上部根部。

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

安岩中包含斜长（中长或奥长），是在正长组成的细粒基质中的大单晶体（斑晶）。
