latite

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

安粗岩中包含（中或奥），是在正和普通辉组成细粒基质中大单体（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.

岩、矿物地球化学研究表明，辉粗安岩与辉二岩同源，分别为火山上部和根部。
