Rhyolite is a type of volcanic rock that is formed from the rapid cooling and solidification of magma or lava that is rich in silica content.

It is typically light-colored, ranging from pale gray to pink or even reddish-brown, and has a fine-grained texture due to its rapid cooling process. Rhyolite often contains various mineral crystals, such as quartz, feldspar, and mica.
