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，辉岩与辉二长岩同源，分为火山穹窿的上和根。

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

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