Rhyolite, extrusive igneous rock that is the volcanic equivalent of granite.Most rhyolites are porphyritic, indicating that crystallization began prior to extrusion. Rhyolite is a silica-rich rock, usually occurring in white to gray to pale pink shades. ... gabbro, granite, dacite, obsidian, pumice, pegmatite, peridotite, rhyolite, scoria, and tuff. There are a good amount of types of igneous rocks you can find, in … Is rhyolite an intrusive or extrusive rock? Extrusive cooling. 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. These rocks include: andesite, basalt, dacite, obsidian, pumice, rhyolite, scoria, and tuff. Igneous Rock Types: Igneous rocks can be described as being either intrusive or extrusive. Andesite is an extrusive igneous rock that is higher in silica than basalt and lower than rhyolite or felsite. Extrusive. Which graph best represents the textures of granite, pegmatite, and rhyolite? Rhyolite, an extrusive igneous rock, is the chemical equivalent of the intrusive igneous rock granite. Rhyolite. Rhyolite lavas are highly viscous, and tend to explode when coming in contact with the air as they’re ejected from volcanoes. Intrusive vs extrusive igneous rocks Name: Date: 1. Crystallization may sometimes have begun while the magma was deeply buried; in such cases, the rock may consist principally of well-developed, large, single crystals (phenocrysts) at the time of extrusion. Which rock is usually light grayish-pink? What type of igneous rock is rhyolite (intrusive or extrusive)? It is the chemical equivalent of granite. Extrusive cooling refers to the way in which igneous volcanic rocks are created. Igneous rock formed through extrusive cooling is first extruded to … Some cool so quickly that they form an amorphous glass. In general, color is a good clue to the silica content of extrusive igneous rocks, with basalt being dark and felsite being light.
