Rhyolite And Granite Are Alike In That They Both Are

Granite is plutonic and rhyolite is volcanic.

Rhyolite and granite are alike in that they both are. Rhyolite is a silica rich igneous rock found throughout the world. They have essentially the same composition. Crystallization may sometimes have begun while the magma was deeply buried. Rhyolite is similar in composition and appearance to granite but it forms through a.

The difference is that granite sits on the plutonic diagram and rhyolite sits on the volcanic diagram. According to the earth science reference tables rhyolite and granite are alike in that they both are. Rhyolite extrusive igneous rock that is the volcanic equivalent of granite most rhyolites are porphyritic indicating that crystallization began prior to extrusion. So they have a similar composition but one is volcanic and the other is plutonic.

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. Both granite and rhyolite are felsic igneous rocks formed from very viscous silica rich magma. The difference between them is that granite cools slowly. Granite and rhyolite have essentially the same composition.

Both are felsic igneous rocks meaning they form from molten rock that is rich in silica sodium potassium and aluminum. In such cases the rock may consist principally of well developed large single crystals phenocrysts at the time of extrusion.
