Rhyolite And Granite Are Alike In That They Both Are

Both are felsic igneous rocks meaning they form from molten rock that is rich in silica sodium potassium and aluminum.

Rhyolite and granite are alike in that they both are.

A longer period of time than the other. Larger crystal size in one of two igneous rocks of similar composition usually indicates that the rock with the larger crystals cooled for. Granite is plutonic and rhyolite is volcanic. Rhyolite is a silica rich igneous rock found throughout the world.

In such cases the rock may consist principally of well developed large single crystals phenocrysts at the time of extrusion. The difference between them is that granite cools slowly. Granite and rhyolite have essentially the same composition. Rhyolite extrusive igneous rock that is the volcanic equivalent of granite most rhyolites are porphyritic indicating that crystallization began prior to extrusion.

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. Crystallization may sometimes have begun while the magma was deeply buried. So they have a similar composition but one is volcanic and the other is plutonic. They have very similar compositions but one is erupted onto earth s surface and the other crystallises at.

Both granite and rhyolite are felsic igneous rocks formed from very viscous silica rich magma. Rhyolite is similar in composition and appearance to granite but it forms through a.
