Compare And Contrast The Mineralogical Composition Of Granite And Rhyolite

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. The difference between them is that granite cools slowly. They have essentially the same composition.

Granite Vs Obsidian

Rhyolite is the felsic igneous rock with fine grained size.

Compare and contrast the mineralogical composition of granite and rhyolite. Rocks are composed of different elements and materials. The difference is the size of grains. The difference is the size of grains. Therefore granite has a phaneritic texture while rhyolite is formed extrusively and so has an aphanitic texture.

Whereas granite is the equivalent in composition but with coarse grained size. They are different in that granite forms when magma cools intrusively. Chemical weathering changes the composition of a rock. Whereas granite is the equivalent in composition but with coarse grained size.

Obsidian is likely felsic. 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. 5 2 composition 5 2 1 mineral content.

Both granite and rhyolite are felsic igneous rocks formed from very viscous silica rich magma. The difference is that granite sits on the plutonic diagram and rhyolite sits on the volcanic diagram. Rhyolite forms at much shallower depths and thus is fine grained. Classify each of the following rocks by their mineral composition felsic intermediate or mafic.

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. Granite and rhyolite are similar in that they have the same mineral chemical composition. Rhyolite is the felsic igneous rock with fine grained size. Granite forms deep beneath the surface and therefore is coarse grained.

Rhyolite however is typically not found as often or as voluminous as granite which is found in large deposits all over the place. Compare and contrast granite and rhyolite. Gabbro obsidian granite and andesite. So they have a similar composition but one is volcanic and the other is plutonic.
