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、矿物地球化究表明，辉粗安岩与辉二岩同源，分为火山穹窿上部和根部。

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

安粗岩中包含（中或奥），是在正和普通辉组成细粒基质中大单晶体（斑晶）。
