What Kind Of Rock Is Granite Igneous

The three types of rocks.

What kind of rock is granite igneous.

Magma that rises to the surface is called lava. The two best known igneous rock types are basalt and granite which have distinctly different compositions and textures. Igneous they form from the cooling of magma deep inside the earth. Granite is a light colored igneous rock with grains large enough to be visible with the unaided eye.

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. 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. It is the most common plutonic rock of the earth s crust forming by the cooling of magma silicate melt at depth.

Igneous rocks are formed from the solidification of molten rock material. Granite ˈ ɡ r æ n ɪ t is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture. Examples of intrusive igneous rocks are diabase diorite gabbro granite pegmatite and peridotite. What are igneous rocks.

Basalt is the dark fine grained stuff of many lava flows and magma intrusions. Intrusive igneous rocks crystallize below earth s surface and the slow cooling that occurs there allows large crystals to form. Granite common type of intrusive felsic igneous rock with granular structure granodiorite a phaneritic textured intrusive igneous rock similar to granite granophyre a subvolcanic rock that contains quartz and alkali feldspar in characteristic angular intergrowths. Granite is used by the public as a catchall name for any light colored coarse grained igneous rock.

Igneous rocks from the greek word for fire form when hot molten rock magma crystallizes and solidifies. Learn more about the properties and uses of granite in this article. Granite is composed mainly of quartz and feldspar with minor amounts of mica amphiboles and other minerals this mineral composition usually gives granite a red pink gray or white color with dark mineral. Granite is an igneous rock that forms by slow cooling of granite is possibly the most common igneous rock type known to the general public.

Strictly speaking granite is an. Magma originates deep within the earth near active plate boundaries or hot spots. Photo by eva didonato. It s the first thing you learn in a geology class very briefly the three types of rocks are.

Its dark minerals are rich in magnesium mg and iron fe hence basalt is called a mafic rock. Igneous rock textures sciencestruck. Basalt is an example of a fine crystalline rock that cooled rapidly at the type. There are two basic types.
