latite

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

安粗含斜长石（长石或奥长石），是在正长石普通辉石组成的细粒基质的大单体（斑）。

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.

石、矿物地球化学的研究表明，辉石粗安与辉石二长同源，分别为火山穹窿的上。
