  4.9: Intrusive and Extrusive Igneous Rocks - K12 LibreTexts

  Extrusive igneous rocks form above the surface. The lava cools quickly as it pours out onto the surface ( Figure below). Extrusive igneous rocks cool much more rapidly than intrusive rocks. The rapid cooling time does not allow time for large crystals to form. So extrusive igneous rocks have smaller crystals than igneous intrusive rocks.

  Granite | Composition, Properties, Types, & Uses | Britannica

  Granite, coarse- or medium-grained intrusive igneous rock that is rich in quartz and feldspar; it is the most common plutonic rock of the Earth’s crust, forming by the cooling of magma (silicate melt) at depth. Learn more about the properties and uses of granite in this article.

  3.3: Crystallization of Magma. The minerals that make up igneous rocks crystallize at a range of different temperatures. This explains why a cooling magma can have some crystals within it and yet remain predominantly liquid. The sequence in which minerals crystallize from a magma is known as the Bowen reaction series.

  4.7: Igneous Rocks - Geosciences LibreTexts

  A pluton is an igneous intrusive rock body that has cooled in the crust. When magma cools within the Earth, the cooling proceeds slowly. Slow cooling allows time for large crystals to form, so intrusive igneous rocks have visible crystals. Granite is the most common intrusive igneous rock.Igneous rocks make up most of the rocks on Earth.

  What Is a Phaneritic Texture and Which Rocks Have It?

  202293 · What is the meaning of phaneritic texture? Phaneritic texture describes the texture of igneous rocks with large mineral crystals visible by the unaided eye, meaning you can distinguish the minerals present with the naked eye. Such a texture is also considered coarse-grained and is typical of intrusive or plutonic rocks like granite, gabbro, or diorite.
