Rhyolite is an igneous, rock, of silica-rich composition (> 69% SiO2). The mineral assemblage is usually quartz, alkali feldspar and plagioclase (in a ratio > 1:2), Biotite and hornblende are common accessory minerals.
Phyllite could contain mica, chlorite, talc, graphite, among other minerals.
Phillite can be found in Easten North America,the Appalachians, the Alps,and the Scottish Highlands. :P
Phyllite is found in most regionally metamorphosed terranes in the world, including the Appalachians of eastern North America, the Scottish Highlands, and the Alps.
The parent rocks of gneiss include mudstone, shale, slate, phyllite, schist, granite, or diorite. The parent rocks of phyllite only include mudstone, shale, or slate.
