A coarse-grained plutonic igneous rock, considered a specific variety of granite or quartz monzonite, in which potassium feldspar and plagioclase feldspar (especially oligoclase or andesine) are present in approximately equal amounts. This crystalline rock also contains abundant quartz and ferromagnesian minerals such as biotite or hornblende, commonly found in ancient mountain massifs.
