Rhyolite is the general term for a type of volcanic rock, occurring mostly as lava flows, and characterized by a highly acid composition. Vesicular and/or spherulitic structure is very common in rhyolites. The cavities are often lined with opal and tridymite; they may also be filled with agate and chalcedony . Home
Rhyolite, with felsic minerals comprising gt;20% quartz and alkali feldspar/plagioclase 4090%. A group of extrusive igneous rocks, typically porphyritic and commonly exhibiting flow texture, with phenocrysts of quartz and alkali feldspar in a glassy to cryptocrystalline groundmass; also, any rock in that group; the extrusive equivalent of granite.

Rhyolite can be considered as the extrusive equivalent to the plutonic granite rock, and consequently, outcrops of rhyolite may bear a resemblance to granite. Due to their high content of silica and low iron and magnesium contents, rhyolitic magmas form highly viscous lavas.
