What Type of Rock is Granite? - Arizona Tile

Sep 18, 2020 · Granite is a type of igneous rock. This means that it was formed in the earth over time by slowly cooling magma. As the magma cools, it hardens into granite, which is one of the most common types of stone found within the earth. Named for its granular texture, granite is composed of a variety of different minerals.

Feb 15, 2017 · Igneous rocks form when liquid magma (molten rock) cools and hardens. In the hardening, minerals take on their shape, or crystallize. There are two basic subcategories of igneous rocks—intrusive and extrusive. When the magma cools within Earth’s crust, the rocks are of the intrusive igneous type. Granite is the most common rock of this type.

Rhyolite is a felsic (silica-rich) volcanic igneous rock with the same mineral content as granite, only unlike granite, it cools fast from the molten rock near or over the surface of Earth's crust (extrusive type).When these magmas erupt, a rock with two grain sizes typically forms. The larger crystals that form just beneath the surface cool at a slower pace and are known as phenocrysts.
