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

安粗岩中包石（中石或奥石），是在正石和普通辉石组成细粒基质中大单晶体（斑晶）。

The feldspar group contains tectosilicate minerals with similar properties, including orthoclase, albite and labradorite. Feldspars make up more than 60% of the upper crust of the earth.
