Wikipedia
Rhyolite is an igneous, volcanic rock, of felsic ( silica-rich) composition (typically > 69% SiO—see the TAS classification). It may have any texture from glassy to aphanitic to porphyritic. The mineral assemblage is usually quartz, sanidine and plagioclase (in a ratio > 2:1—see the QAPF diagram). Biotite and hornblende are common accessory minerals. It is the extrusive equivalent to granite.
