Compare And Contrast The Mineralogical Composition Of Granite And Rhyolite

Granite is an intrusive igneous rock which is very hard crystalline and is visibly homogeneous in texture and forms by melting of continental rocks rhyolite is a felsic extrusive rock and due to its high silica content rhyolite lava is very viscous and is volcanic equivalent of granite.

Compare and contrast the mineralogical composition of granite and rhyolite.

Rhyolite however is typically not found as often or as voluminous as granite which is found in large deposits all over the place. Rhyolite forms at much shallower depths and thus is fine grained. Granite forms deep beneath the surface and therefore is coarse grained. They have essentially the same composition.

They are different in that granite forms when magma cools intrusively. The difference between them is that granite cools slowly. Granite and rhyolite are similar in that they have the same mineral chemical composition. Rhyolite is the felsic igneous rock with fine grained size.

Compare and contrast granite and rhyolite. So they have a similar composition but one is volcanic and the other is plutonic. Classify each of the following rocks by their mineral composition felsic intermediate or mafic. Both granite and rhyolite are felsic igneous rocks formed from very viscous silica rich magma.

Obsidian is likely felsic. Chemical weathering changes the composition of a rock. Therefore granite has a phaneritic texture while rhyolite is formed extrusively and so has an aphanitic texture. Rhyolite is the felsic igneous rock with fine grained size.

The difference is the size of grains. Felsic rocks are a type of igneous rock that are comprised of light. How are granite and rhyolite the same and how do they differ. Whereas granite is the equivalent in composition but with coarse grained size.

The difference is that granite sits on the plutonic diagram and rhyolite sits on the volcanic diagram. The difference is the size of grains. 5 2 composition 5 2 1 mineral content. As nouns the difference between granite and rhyolite is that granite is rock a group of igneous and plutonic rocks composed primarily of feldspar and quartz usually contains one or more dark minerals which may be mica pyroxene or amphibole granite is quarried for building stone road gravel decorative stone and tombstones common colors are gray white pink and yellow brown while.
