Granite
Felsic intrusive igneous rock composed primarily of quartz, feldspar (orthoclase and plagioclase), and mica (biotite and/or muscovite).
Also known as: Granitic rock
Schist
Medium-grade metamorphic rock characterized by strong foliation (schistosity) and often containing abundant mica (muscovite, biotite) and quartz.
Also known as: Schistose rock
Gneiss
High-grade metamorphic rock characterized by distinct banding (gneissic banding) of light (quartz, feldspar) and dark (biotite, hornblende) minerals. Muscovite can also be present.
Also known as: Gneissic rock
Pegmatite
Extremely coarse-grained igneous rock, typically granitic in composition, often containing large crystals of quartz, feldspar, and mica (muscovite, biotite).
Also known as: Giant-grained igneous rock
