Definition
Granite is a very hard, granular, crystalline igneous rock which consists mainly of quartz, mica, and feldspar and is often used as building stone
Mylonite is a metamorphic rock formed by ductile deformation during intense shearing encountered during folding and faulting, a process termed cataclastic or dynamic metamorphism

Formation
Granite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks
Mylonites are ductilely deformed rocks formed by the accumulation of large shear strain, in ductile fault zones.

More about Granite and Mylonite
Here you can know more about Granite and Mylonite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granite and Mylonite consists of mineral content and compound content. The mineral content of Granite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz and mineral content of Mylonite includes Porphyroblasts. You can also check out the list of all Igneous Rocks. When we have to compare Granite vs Mylonite, the texture, color and appearance plays an important role in determining the type of rock. Granite is available in black, grey, orange, pink, white colors whereas, Mylonite is available in black to grey colors. Appearance of Granite is Veined or Pebbled and that of Mylonite is Dull, Banded and Foilated. Properties of rock is another aspect for Granite vs Mylonite. The hardness of Granite is 6-7 and that of Mylonite is 3-4. The types of Granite are Igneous Protolith Granite, Sedimentary Protolith Granite, Mantle Granite, Anorogenic Granite, Hybrid Granite, Granodiorite and Alkali Feldspar Granite whereas types of Mylonite are Blastomylonites, Ultramylonites and Phyllonites. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granite and Mylonite is white. The specific heat capacity of Granite is 0.79 kJ/Kg K and that of Mylonite is 1.50 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Granite is heat resistant, wear resistant whereas Mylonite is heat resistant, impact resistant, pressure resistant.
