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.
Kinds of Metamorphic Rocks. 1  Slate - low grade metamorphosed shale; very fine grained; slaty cleavage should not be confused with bedding planes. 2  Phyllite - next step up from slate, larger mica grains give the rock a luster.  Schist - a strongly foliated rock with large grains of platy minerals.
