Granite is an igenous rock that was formed via solidification of a magma several kilometers deep in the crust.

Granite is mineralogically defined a s a rock that has a quarz/feldspar ratio of 0.2 to 0.6, and has a ratio of alkali feldspars vs plagioclase of 1/3 to 0.9.

Furthermore Quarz and feldspars must make up more than 10 % of the minerals of the rock and it may not have been deformed to become a metamorphic rock (gneiss).

Chemically granite is defined as the igneous rock type richest in silicon.
