Granite and basalt are

Granite and Basalt are examples of Igneous rocks, which are formed by the solidification and crystallization of magma.
Granite is a coarse-grained intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground.
Basalt is a fine-grained extrusive igneous rock formed from the rapid cooling of low viscosity lava rich in magnesium and iron exposed at or very near the surface of a rocky planet or moon.
