The rock received its name from german geologist ferdinand von richthofen better known as the red baron a world war i flying ace the word rhyolite comes from the greek word rhýax a stream of lava with the suffix ite given to rocks.

Rhyolite and granite are alike in that they both are.

The difference between them is that granite cools slowly. Rhyolite extrusive igneous rock that is the volcanic equivalent of granite most rhyolites are porphyritic indicating that crystallization began prior to extrusion. Both granite and rhyolite are felsic igneous rocks formed from very viscous silica rich magma. They have essentially the same composition.

So they have a similar composition but one is volcanic and the other is plutonic. Granite is plutonic and rhyolite is volcanic. The difference is that granite sits on the plutonic diagram and rhyolite sits on the volcanic diagram. Crystallization may sometimes have begun while the magma was deeply buried.

They have very similar compositions but one is erupted onto earth s surface and the other crystallises at. Both are felsic igneous rocks meaning they form from molten rock that is rich in silica sodium potassium and aluminum. Larger crystal size in one of two igneous rocks of similar composition usually indicates that the rock with the larger crystals cooled for. Rhyolite is similar in composition and appearance to granite but it forms through a.

According to the earth science reference tables rhyolite and granite are alike in that they both are. Granite and rhyolite have essentially the same composition.
