Characteristics A body of intrusive igneous rock which crystallizes from magma cooling underneath the surface of the Earth is called a pluton.If the pluton is large, it may be called a batholith or a stock depending on the area exposed at the surface. Examples include … Because lava cools more quickly, there is not enough time for mineral crystals to form and grow, so you have rocks with very tiny mineral crystals that cannot be seen without the aid of a magnifier. If they erupt from volcanoes onto the surface as lava, they are called extrusive rocks.By contrast, Intrusive rocks are formed from magma that cools underground. The intrusive igneous rocks that forms below the surface of the earth are termed as plutonic and are coarse grained whereas the intrusive igneous rock formed near the surface is known as subvolcanic and are medium grained.
