2016年3月13日 · Summary: Granite is plutonic and rhyolite is volcanic. They have very similar compositions but one is erupted onto Earth's surface and the other crystallises at depth. As a result, plutonic rocks are coarse-grained and volcanic rocks are fine-grained.

2024年4月28日 · Rhyolite, with its fine-grained texture and rapid surface cooling, stands apart as a product of explosive volcanic activity, while granite’s coarse-grained structure, formed from slow underground cooling, renders it durable and resistant to weathering.

Rhyolite is a fine-crystalline felsic extrusive rock. Rhyolite is commonly pink and will often have glassy quartz phenocrysts. Because felsic lavas are less mobile, it is less common than granite.

When we have to compare Granite vs Rhyolite, the texture, color and appearance plays an important role in determining the type of rock. Granite is available in black, grey, orange, pink, white colors whereas, Rhyolite is available in grey, white, light black colors.

Hint: Rhyolite and granite have similar composition. The difference between them is that rhyolite is an intrusive igneous rock whereas granite is an extrusive igneous rock. 0ne is formed within the earth's crust, another is formed near or on the earth’s surface.

As nouns the difference between granite and rhyolite is that granite is 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.

Rhyolite is an extrusive igneous rock having cooled much more rapidly than granite, giving it a glassy appearance. The minerals that make up rhyolite are quartz, feldspar, mica, and hornblende. Pumice is a very light colored, frothy volcanic rock.

2019年6月2日 · Rhyolite is a high-silica volcanic rock that is chemically the same as granite but is extrusive rather than plutonic. Click the photo for the full-size version. Rhyolite lava is too stiff and viscous to grow crystals except for isolated phenocrysts.

2022年4月2日 · Do granite and rhyolite have the same chemical composition? For example, a felsic intrusive rock is called granite, whereas a felsic extrusive rock is called rhyolite. Granite and rhyolite have the same mineral composition , but their grain size gives each a distinct appearance.
