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

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

Mylonite vs Granite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Mylonite vs Granite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Mylonite and Properties of Granite. Learn more about Mylonite vs Granite in the next section. The interior uses of Mylonite include Decorative aggregates and Interior decoration whereas the interior uses of Granite include Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels, Interior decoration, Kitchens and Stair treads. Due to some exceptional properties of Mylonite and Granite, they have various applications in construction industry. The uses of Mylonite in construction industry include For road aggregate, Landscaping, Roadstone and that of Granite include As dimension stone.
More about Mylonite and Granite
Here you can know more about Mylonite and Granite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mylonite and Granite consists of mineral content and compound content. The mineral content of Mylonite includes Porphyroblasts and mineral content of Granite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Mylonite vs Granite, the texture, color and appearance plays an important role in determining the type of rock. Mylonite is available in black to grey colors whereas, Granite is available in black, grey, orange, pink, white colors. Appearance of Mylonite is Dull, Banded and Foilated and that of Granite is Veined or Pebbled. Properties of rock is another aspect for Mylonite vs Granite. The hardness of Mylonite is 3-4 and that of Granite is 6-7. The types of Mylonite are Blastomylonites, Ultramylonites and Phyllonites whereas types of Granite are Igneous Protolith Granite, Sedimentary Protolith Granite, Mantle Granite, Anorogenic Granite, Hybrid Granite, Granodiorite and Alkali Feldspar Granite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Mylonite and Granite is white. The specific heat capacity of Mylonite is 1.50 kJ/Kg K and that of Granite is 0.79 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Mylonite is heat resistant, impact resistant, pressure resistant whereas Granite is heat resistant, wear resistant.
