Rhyolite is a silica-rich rock, usually occurring in white to gray to pale pink shades. Which graph best represents the textures of granite, pegmatite, and rhyolite? Although the two rock types have the same chemistry, rhyolite is extrusive and granite is intrusive. Rhyolite is a relatively common volcanic rock. An igneous rock is either an intrusive or extrusive rock and can have one or a multiple variety of minerals within it. Rhyolite, extrusive igneous rock that is the volcanic equivalent of granite.Most rhyolites are porphyritic, indicating that crystallization began prior to extrusion. B. C. D. 2. Rhyolite.
