In most rhyolites however it is sanidine not infrequently rich in soda. The difference is the size of grains. Both rhyolite and basalt are types of igneous rocks igneous rocks are usually found in two forms as intrusive and extrusive igneous rocks based on the method of formation.

A plutonic igneous rock is one that crystallises. Certain differences between rhyolite and granite are noteworthy. Rhyolite is a felsic extrusive rock and due to its high silica content rhyolite lava is very viscous and is volcanic equivalent of granite. Rhyolite is similar in composition and appearance to granite but it forms through a.

Properties of rock is another aspect for granite vs rhyolite. Rhyolite is a silica rich igneous rock found throughout the world. What is the fundamental difference between diorite and andesite. What are the fundamental differences between basalt and rhyolite.
