Rhyolite is a type of extrusive igneous rock characterised by its light color, high silica content, and fine-grained texture. It forms from the rapid cooling of magma on the Earth's surface and is often associated with volcanic eruptions. Rhyolite is rich in silica (SiO₂), typically containing more than 70% silica. It is composed mainly of quartz and feldspar, with minerals like biotite, hornblende, and pumice often present.
