What basic type of rock is granite.

The three types of rocks. Students of granites classify them in three or four categories. Granite ˈ ɡ r æ n ɪ t is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture. Any unique combination of chemical composition mineralogy grain size texture or other distinguishing characteristics can describe a rock type.

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. It is the most common plutonic rock of the earth s crust forming by the cooling of magma silicate melt at depth. Igneous they form from the cooling of magma deep inside the earth. Granite coarse or medium grained intrusive igneous rock that is rich in quartz and feldspar.

Additionally different classification systems exist for each major type of rock. 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 s the first thing you learn in a geology class very briefly the three types of rocks are. Learn more about the properties and uses of granite in this article.

Granite is a common type of granular and phaneritic felsic intrusive igneous rock granites depending on their mineralogy can be predominantly white pink or gray in colour. Granite is one of the most commonly known types of rocks used in everything from buildings to sculptures.
