Granite is a felsic rock.
Is granite mafic.
Syenite diorite and monzonite are intermediate with an average silica content of 59 percent.
In contrast felsic rocks are rich in silica sodium and potassium.
Granite is composed mainly of quartz and feldspar with minor amounts of mica amphiboles and other minerals this mineral composition usually gives granite a red pink gray or white color with dark mineral.
Overall granite is a felsic rock with mafic minerals being secondary or accessory in nature.
Basalt is the opposite of granite.
Mafic rocks are relatively rich in iron magnesium and calcium.

Granites can be predominantly white pink or gray in color depending on their mineralogy the word granite comes from the latin granum a grain in reference to the coarse grained structure of such a completely crystalline rock.
Felsic rocks are less dense than mafic and ultramafic rocks and thus they tend to escape subduction whereas basaltic or gabbroic rocks tend to sink into the mantle beneath the granitic rocks of the continental cratons.
Basalt is a mafic dark coloured minerals rich in iron and magnesium fine grained rock formed from the rapid cooling and crystallisation of lava above ground.

Rhyolite is not a mafic rock but a felsic rock high in silicates and similar to granite in composition.
Compilations of many rock analyses show that rhyolite and granite are felsic with an average silica content of about 72 percent.
Width of sample from norway is 10 cm.
Granite is not a mafic rock.
