Is granite a igneous rock. Granite type rocks granitoids are abo. It is the most common plutonic rock of the earth s crust forming by the cooling of magma silicate melt at depth. Coarse grained granite is most similar in mineral composition to fine grained. Granite is an intrusive igneous rock.

Granite is the most widespread of igneous rocks underlying much of the continental crust. Granite ˈ ɡ r æ n ɪ t is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture. Intrusive rocks form from molten material magma that flows and solidifies underground where magma cools slowly. 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.

Partial melt granitic type rocks are granitic gneiss which is a metamorphic rock. Granite coarse or medium grained intrusive igneous rock that is rich in quartz and feldspar. It is made of a mixture of quartz and feldspar and it s very hard. Granite is an igneous intrusive rock crystallized at depth with felsic composition rich in silica and predominately quartz plus potassium rich feldspar plus sodium rich plagioclase and phaneritic subeuhedral texture minerals are visible to the unaided eye and commonly some of them retain original crystallographic shapes.

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 forms from the slow crystallization of magma below earth s surface. Eventually the overlying rocks are removed exposing the granite. Granite is used by the public as a catchall name for any light colored coarse grained igneous rock.

Granite is an intrusive igneous rock which means it was formed in place during the cooling of molten rock generally the slower the molten rock cooled the larger it s mineral crystals with k feldspar megacrysts forming in special circumstances greater than 5cm.

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.
