Is rhyolite an intrusive or extrusive rock? Igneous rock formed through extrusive cooling is first extruded to … What type of igneous rock is scoria (intrusive or extrusive)? Although the two rock types have the same chemistry, rhyolite is extrusive and granite is intrusive. What type of igneous rock is rhyolite (intrusive or extrusive)? Rhyolite. Extrusive. Some cool so quickly that they form an amorphous glass. Examples of intrusive igneous rocks are: diabase, diorite, gabbro, granite, pegmatite, and peridotite. Rhyolite. Rhyolite, extrusive igneous rock that is the volcanic equivalent of granite.Most rhyolites are porphyritic, indicating that crystallization began prior to extrusion. Click the photo to see the full-size version. Rhyolite lavas are highly viscous, and tend to explode when coming in contact with the air as they’re ejected from volcanoes. Rhyolite is a relatively common volcanic rock. Igneous Rock Types: Igneous rocks can be described as being either intrusive or extrusive. 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.
