By definition, yes. In contrast, aphanitic rocks do not have visible crystals.

Large-size crystals are known as phaneritic .?
Texture
What is the texture of igneous rocks with large crystals that slow cooling produces?
Phaneritic.
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.
What does igneous contain?
Randomly arranged interlocking crystals and no fossils :)

Phaneritic.
Is gabbro a phaneritic rock?
Yes, Gabbro is a phaneritic igneous rock.
How can you identify an igneous rock?
Intrusive igneous rock is composed of visible mineral crystals, possessing what is referred to as a phaneritic texture. This is evidence that slow cooling of magma occurred deep underground.
What observation about an igneous rock would support the inference that the rock cooled slowly underground?
The rock would have visible mineral crystals--a phaneritic texture.
What is a type of mafic phaneritic rock?
Gabbro is a type of mafic, phaneritic igneous rock.
How is the size of mineral crystals in igneous rock related to the rate at which they cool?
When igneous rocks cool quickly, they have small crystals and have a texture that may be described as aphanitic. When igneous rocks cool slowly, they have much larger crystals and have a texture that may be described as phaneritic or pegmatitic.

Do extrusive igneous rocks contain crystals?
No. Pure volcanic glasses contain no crystalline structure.
What kind of igneous rock texture results from slow cooling magma?
A coarse grained texture, referred to as a phaneritic texture, will be the resultant igneous rock texture. The slower the magma cools the more time minerals have to crystallize and thus grow bigger.
