If magma cools slowly deep within the crust the resulting rock is called intrusive or plutonic.

Background from solid stone. Granite also tends to have coarse intergrowths of feldspars and quartz that form a graphic texture. It is coarse to medium grained. The different colors are unique minerals.

Durable rocks novaculite. Granites can be predominantly white pink or gray in color depending on their mineralogy. Granite is a classic coarse grained phaneritic intrusive igneous rock. It was formed from slow cooling viscous magma and or good nucleation.

Granite has a phaneritic texture. Petrographic examination is required for identification of specific types of granitoids. Pattern with natural material. Granitoid is a general descriptive field term for lighter colored coarse grained igneous rocks.

The black colors are likely two or three different minerals. It is classified as acid plutonic igneous rock and it commonly occurs in batholiths. The overall color of granite depends largely on the kind of feldspar in the rock. This means that it has crystals 1 10 mm.

Granite is composed mainly of quartz and feldspar with minor amounts of mica amphiboles and other minerals.
