Granite is a coarse-grained (phaneritic), plutonic, igneous rock
rich in
orthoclase feldspar and quartz.
Some albite (sodium plagioclase feldspar)
may also
be present.
Accessory minerals are
commonly
muscovite, biotite, or hornblende.
It is the orthoclase feldspar that
imparts a pink to red color of granite.
