Picture granite igneous rock. Granite is a type of igneous rock that consists of quartz gray plagioclase feldspar white and alkali feldspar beige plus dark minerals such as biotite and hornblende. This is also called a plutonic rock. Granite is thought to form as hot fluids from deeper in the mantle rise and trigger widespread melting in the continental crust. Anorthosite a mafic intrusive igneous rock composed predominantly of plagioclase.

Granite is used by the public as a catchall name for any light colored coarse grained igneous rock. Igneous rocks are formed from the solidification of molten rock material. Alkali feldspar granite a granitoid in which at least 90 of the total feldspar is alkali feldspar. Aplite a fine grained intrusive igneous rock.

There are two basic types. What are igneous rocks. Adakite a class of intermediate to felsic volcanic rocks containing low amounts of yttrium and ytterbium. Granite is a light colored igneous rock with grains large enough to be visible with the unaided eye.

Diorite is a coarse grained igneous rock that forms when the magma did not erupt but instead slowly crystallized within earth s crust. Examples of intrusive igneous rocks are diabase diorite gabbro granite pegmatite and peridotite. Andesite and diorite have a composition that is intermediate between basalt and granite. Granites can be predominantly white pink or gray in color depending on their mineralogy the word granite comes from the latin granum a grain in reference to the coarse grained structure of such a completely crystalline rock.

It forms from the slow crystallization of magma below earth s surface. Intrusive igneous rocks crystallize below earth s surface and the slow cooling that occurs there allows large crystals to form. Andesite is a fine grained rock that formed when the magma erupted onto the surface and crystallized quickly. Uses of granite the rock used everywhere from the kitchen to the facing stone of skyscrapers.

Andesite an intermediate volcanic rock. Photos descriptions and facts about intrusive and extrusive igneous rocks.
