Which two igneous rocks have phaneritic textures?
Even in the most generalized classification, more than two igneous rocks have phaneritic textures. In that generalized classification, they are granite, diorite, gabbro, and peridotite.
What is the texture of igneous rocks with large crystals that slow cooling produces?
Phaneritic.
Do phaneritic igneous rocks contain viewable crystals?
By definition, yes. In contrast, aphanitic rocks do not have visible crystals.
Is gabbro a phaneritic rock?
Yes, Gabbro is a phaneritic igneous rock.
What does phaneritic mean?
Phaneritic refers to igneous rock grain size,which is visible with the naked eye.
Rocks with visible crystals display what is known as a phaneritic 'blank'?
The display a phaneritic texture.
Is granite a phaneritic rock?
Granite is a phaneritic rock. Phaneritic rocks are coarse-grained, and they have visible crystals. Other phaneritic rocks include diorite, gabbro, and periodite. These rocks are also intrusive because they cool slowly.
What is the texture of igneous rock?
Phaneritic is the texture of igneous rocks. These types of rocks crystallized slowly.
Describe the textural difference between coarse-grained phaneritic and fine-grained aphaneritic rocks?
describe the textural difference between coarse-grained (phaneritic) and fine-grained (aphaneritic) rocks

Even in the most generalized classification, more than two igneous rocks have phaneritic textures. In that generalized classification, they are granite, diorite, gabbro, and peridotite.
What is the texture of igneous rocks with large crystals that slow cooling produces?
Phaneritic.
Do phaneritic igneous rocks contain viewable crystals?
By definition, yes. In contrast, aphanitic rocks do not have visible crystals.
What are rocks that have visible crystals in them classified as?
Rocks with easily visible mineral crystals are called macrocrystalline or said to possess a phaneritic texture.
What is the textural difference between coarse-grained phaneritic and fine-grained aphaneritic rocks?
Coarse grained textured rocks (phaneritic) have very large crystals because the magma, from which they are created, cools very slowly. Fine grained rocks (aphaneritic) have small crystals because the lava, from which they are created, cools down very quickly.
INTRUSIVE IGNEOUS ROCK ARE NOTED FOR?
Intrusive rocks, also called plutonic rocks, cool slowly without ever reaching the surface. They have large crystals that are usually visible without a microscope. This surface is known as a phaneritic texture. Perhaps the best-known phaneritic rock is granite
Plutonic rocks are characterized by which type of texture?
Plutonic rocks have a phaneritic texture. It is characterized by interlocking crystals of several minerals that are easily visible and randomly distributed. .
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
