Is diorite's texture a aphanitic?
Yes diorite's texture is aphanitic.
What kind of texture will an igneous rock have if it cooled very quickly and you can not see crystals?
The texture thus described is referred to as aphanitic texture.
Which igneous rocks exhibit aphanitic texure?
Normally, extrusive igneous rocks exhibit an aphanitic texture. Examples would be basalt and rhyolite.
What is Andesite texture?
Andesite texture is fine-grained and Extrusive plus it a type of igneous rock.
What type of texture do extrusive rock such as basalt have?
Small grained texture from small crystal size.

Which igneous rocks exhibit aphanitic texure?
Normally, extrusive igneous rocks exhibit an aphanitic texture. Examples would be basalt and rhyolite.
If there are small crystals in a rock what is it called?
The rock is said to have a fine-grained texture, also referred to as an aphanitic texture.
Small grained rocks have what texture?
Fine grained rocks are considered aphanitic.
What is Andesite texture?
Andesite texture is fine-grained and Extrusive plus it a type of igneous rock.
What type of texture do extrusive rock such as basalt have?
Small grained texture from small crystal size.
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
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)
What is igneous rock with small crystals called?
The rock is said to be extrusive or possess an aphanitic texture, as a result of relatively rapid cooling.
A rock that cools very quickly so that few or no mineral grains form is?
You can describe the rock by the process that allowed it to cool quickly: "Extrusive" or you can describe it by its texture: "aphanitic". An extrusive rock tends to be aphanitic = Rocks formed from lava flows tend to have small crystals.
Is andesite phaneritic or aphanitic?
Andesite may be aphanitic or porphyritic.
