✓Rhyolite is extrusive, which means it is igneous volcanic rock that is formed from volcanic magma that flows or explodes into the atmosphere, making it the chemical equivalent of granite. It is rich in silicon with a texture that can be glassy, fine grain or a mixture of crystal sizes. Many gem deposits can be found in rhyolite. Natural rhyolite displays green, cream and occasional brown tones with patterns and inclusions.
✓Rhyolite has been found in volcanic mountain ranges in Europe (especially Germany), as well as the Andes, Cascade Range, the Rocky Mountains and other volcanic regions in the Americas, Australia, Asia and Oceania. Group: Volcanic; Chemical Composition: SiO2; Color: Opaque, variable: grey, green, cream and occasional brown and red tones; Hardness: 6 to 6-1/2 (Mohs).
✓Rhyolite is a rock that is rarely used in construction or manufacturing. It is often vuggy or highly fractured. Its composition is variable. When better materials are not locally available, rhyolite is sometimes used to produce crushed stone. People have also used rhyolite to manufacture stone tools, particularly scrapers, blades, and projectile points. It was probably not their material of choice, but a material used out of necessity.
