Granite
Peridotite is a dense, coarse-grained igneous rock.
Pegmatite texture is a coarse-grained igneous rock texture characterized by exceptionally large crystals. These crystals can be several centimeters to several meters in size. The slow cooling of molten rock in pegmatite formations allows for the growth of such large crystals.
Granite, diorite, and gabbro are examples of igneous rocks that do not have a glassy texture. These rocks are formed from slowly cooled magma underground, allowing time for crystals to grow, giving them a coarse-grained appearance.
Gabbro is a coarse-grained igneous rock that is different from granite. It forms from the slow cooling of magma deep within the Earth's crust and is composed mainly of dark-colored minerals like pyroxene and olivine. Gabbro typically has a similar coarse texture to granite but has a darker color due to its mineral composition.
No, granite is a coarse-grained igneous rock that is made up of minerals like quartz, feldspar, and mica. Glassy igneous rocks, like obsidian, form when molten lava cools quickly on the surface, resulting in a smooth, glass-like texture.

Intrusive igneous rock has a coarse, visible crystalline texture. Intrusive igneous rocks are formed from slow cooling of magma. The additional time spent in a liquid state allows for the creation of larger mineral crystals. An igneous rock with a coarse texture is said to be phaneritic.
Peridotite is a dense, coarse-grained igneous rock.
It is most likely formed underground.
The size of crystals in an igneous rock is called texture. Texture can range from fine-grained (small crystals) to coarse-grained (large crystals).
Pegmatite texture is a coarse-grained igneous rock texture characterized by exceptionally large crystals. These crystals can be several centimeters to several meters in size. The slow cooling of molten rock in pegmatite formations allows for the growth of such large crystals.
Gneiss which is a non-foliated meta-igneous rock is coarse grained in texture.
The texture of an igneous rock formed from cooling magma deep beneath the earth is typically coarse-grained. This is because the slower cooling process allows larger mineral crystals to form within the rock.
The texture of an igneous rock that formed extremely slowly underground would likely be coarse-grained. This slow cooling process allows for the growth of large mineral crystals within the rock, leading to a visibly grainy texture.
Granite is the name applied to coarse-grained felsic igneous rocks. These rocks are primarily composed of quartz, feldspar, and mica minerals, giving them a light color and coarse texture.
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.
