It is a type of foliated metamorphic rock that is produced by the metamorphism of shale. Granites are generally very hard and resistant rocks. The changes that occur in the process of metamorphism are because of the changes in the physical pressure and temperature, which alters the mineral composition and texture of the pre-existing igneous and sedimentary rocks to form metamorphic rocks. The extensively known example of non-foliated metamorphic rock is a marble. Because of its properties after metamorphism, it is considered highly used in a wide range of artistic and architectural works. Foliated metamorphic rocks are formed from direct exposure to pressure and heat. Geologists say it represents the intermediate metamorphic grade between gneiss and phyllite.
