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.
