[5]:20, Rhyolites that cool too quickly to grow crystals form a natural glass or vitrophyre, also called obsidian. Rhyolite, Nevada. Extrusive igneous rocks are formed when lava, that is released from the ground, cools pretty quickly on the surface of the Earth. If the process of cooling of magma is slow, taking thousands or perhaps millions of years, such as below the ground, the minerals recrystallize large enough to be seen with the naked eye. When lava, due to its high viscosity and accumulated gases, reaches the surface, it explodes violently into the atmosphere, and falls as pyroclastic fragments back to the ground. The fractionation of igneous rocks is an important process for the geological changes occurring in the Earth. Rhyolite is composed principally of quartz and feldspar minerals, and traces of biotite, plagioclase, mica, amphibiotes, and pyroxenes.
