Granite ([pronˈɡrænᵻt]) is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture. Strictly speaking, granite is an igneous rock with between 20 % and 60 % quartz by volume, and at least 35 % of the total feldspar consisting of alkali feldspar, although commonly the term "granite" is used to refer to a wider range of coarse grained igneous rocks containing quartz and feldspar. These rocks mainly consist of feldspar, quartz, mica, and amphibole minerals, which form an interlocking, somewhat equigranular matrix of feldspar and quartz with scattered darker biotite mica and amphibole (often hornblende) peppering the lighter color minerals. Granitoid is a general, descriptive field term for lighter-colored, coarse-grained igneous rocks. Granite domes are domical hills composed of granite with bare rock exposed over most of the surface.
