Granitic lava flows called rhyolitic when they form at the surface are rare and do not cover much ground. 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.

As the lava quickly cools the trapped gas is unable to escape and forms cavities known as vugs later when the lava flow has. The thick granitic lava that forms rhyolite often cools quickly while pockets of gas are still trapped inside of the lava.
