Phaneritic crystals are typically larger than 1 millimeter in size. They are coarse-grained and can be easily seen with the naked eye due to their size. This texture indicates slow cooling and crystallization of the rock they are formed in.
Texture
By definition, yes. In contrast, aphanitic rocks do not have visible crystals.
Yes, Gabbro is a phaneritic igneous rock.
The texture of igneous rocks with large crystals that form from slow cooling is called phaneritic. This texture indicates that the minerals had enough time to grow large enough to be visible to the naked eye. Examples of rocks with phaneritic texture include granite and diorite.
Granite, diorite, and gabbro are examples of phaneritic rocks. These rocks have coarse-grained textures due to their slow cooling underground, allowing large mineral crystals to form.

Large size crystals that are known as phaneritic are typically found in intrusive igneous rocks. These rocks cool slowly beneath the Earth's surface, allowing the crystals time to grow to visible sizes. Phaneritic textures are characterized by crystals that are easily visible to the naked eye.

A rock with large crystals indicates that the rock cooled slowly. It is referred to as a phaneritic texture when a rock forms this way.
Granite, diorite, and gabbro are examples of phaneritic rocks. These rocks have coarse-grained textures due to their slow cooling underground, allowing large mineral crystals to form.
Andesite can be either phaneritic or aphanitic depending on how it formed. Phaneritic andesite has larger crystals that are visible to the naked eye, suggesting slower cooling and crystallization deep within the Earth's crust. Aphanitic andesite has smaller crystals that are only visible under a microscope, indicating faster cooling at or near the Earth's surface.
A rock with large crystals typically has a coarse texture. The large crystals are easily visible and may feel rough to the touch due to their size.
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.
