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

安岩包含斜长石（长石或奥长石），是在正长石和普通辉石组成细基质大单晶体（斑晶）。

In order to determine the time sequence of recent eruption in Tianchi volcano, the TL thermal-stability has been investigated for pumice and sanidine phenocryst within the volcanics.
