Is rhyolite's texture a aphanitic?
Rhyolite may be aphanitic or porphyritic.
Which igneous rocks exhibit aphanitic texure?
Normally, extrusive igneous rocks exhibit an aphanitic texture. Examples would be basalt and rhyolite.
Is granite rock porphyritic?
Granite rock is not porphyritic. It is phaneritic because it has a coarse-grained texture.
Large-size crystals are known as phaneritic .?

Is diorite's texture a aphanitic?
Yes diorite's texture is aphanitic.
Is rhyolite's texture a aphanitic?
Rhyolite may be aphanitic or porphyritic.

What is the origin of rhyolite?
Rhyolite forms when the felsic magma (greater than 63% SiO2 by weight) came out to the earth surface and can be identified by its aphanitic texture ( The individual crystals in an aphanitic igneous rock are not distinguisable to the naked eye)
Why is the texture of rhyolite different from the texture granite?
because rholite forms outside a volcano and granite forms inside the volcano
Igneous rocks are classified based upon their mineral composition and?
And their texture, which can be aphanitic, phaneritic, glassy, or porphyritic. mineral composition and crystal texture
Is diorite's texture a aphanitic?
Yes diorite's texture is aphanitic.
What is the texture of granit?
Granite has a phaneritic texture. This means that it has crystals 1-10 mm. It was formed from slow cooling, viscous magma, and/or good nucleation. Crystalline. Coarse-grained. Crystals visible without magnification.
Is granite formed from rapidly cooling magma?
No."Granite is formed by the slow cooling & crystallization of magma at some depth in the earth's crust, as indicated by its characteristic phaneritic & phaneritic-porphyritic texture."-The Audubon Society Field Guide to North American Rocks & Minerals
What is the difference between rhyolite and granite?
The difference is the size of grains. Rhyolite is the felsic igneous rock with fine-grained size. Whereas, granite is the equivalent in composition but with coarse-grained size.
What kind of texture does a rock with large crystals have?
A phaneritic texture.
