Granite
Granite is currently known only on Earth where it forms a major part of continental crust.
The volcanic equivalent of plutonic granite is rhyolite.
According to modern petrologic convention true granite contains both alkali feldspars and plagioclase.
Granite is an igneous rock that is formed from magma.
Granite can be pink to dark gray or it even can be black, it just depends on the chemistry and mineralogy mixed together.
Granite comes from the Latin granum, a grain in a reference to the coarse-grained structure of such a crystalline rock.
It is difficult to turn basalt into granite via fractional crystallization.
