You find rhyolite rock wherever you find andesite volcanoes or extinct andesite volcanoes. Topaz Mountain in western Utah (3 hours west of Provo) is a rhyolite mountain complete with garnet, topaz crystals, beryl, and other gemstones and minerals. If there are no dormant or extinct volcanoes in your area, your chances of finding rhyolite are slim to none.
Rhyolite Porphyry is an intrusive rock, formed from the slow cooling of magma underground. It is characterized by large crystals (phenocrysts) surrounded by a fine-grained matrix.
polymineralic igneous rock!
It is a volcanic rock.
Rhyolite is a common rock that forms from light-colored lava. It is composed mainly of silica-rich minerals such as quartz and feldspar, giving it a light color. Rhyolite has a fine-grained texture and often contains small crystals.
Rhyolite is an igneous rock.

Rhyolite is a felsic extrusive igneous rock.
The composition of the rock will determine whether it is a rhyolite or an andesite.
polymineralic igneous rock!
Rhyolite is a rock, not a mineral. Common minerals in it are quartz, orthoclase, and albite. The chief elements in rhyolite are silicon, oxygen, aluminum, sodium, and potassium with other elements in small amounts.
Rhyolite is an igneous, black volcanic rock.
