Granite is Igneous rock. It crystallizes from hot melt (magma). Metamorphic rocks can be found associated with granite as result of their contact with country (surrounding) rocks. This will be a contact metamorphism. Metamorphism of granite it self results into granitic gneisses which are coarse foliated rocks.
Metamorphic rocks have been modified by heat, pressure and chemical processes, usually while buried deep below Earth's surface. Exposure to these extreme conditions has altered the mineralogy, texture and chemical composition of the rocks. There are two basic types of metamorphic rocks.Foliated metamorphic rocks such as gneiss, phyllite, schist, and slate have a layered or banded appearance that is produced by exposure to heat and directed pressure.uartzite is a non-foliated metamorphic rock that is produced by the metamorphism of sandstone. It is composed primarily of quartz. The specimen above is about two inches (five centimeters) across.
