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

Formation
Mylonites are ductilely deformed rocks formed by the accumulation of large shear strain, in ductile fault zones.
Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.

Mylonite vs Granulite 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 Granulite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Mylonite and Properties of Granulite. Learn more about Mylonite vs Granulite in the next section. The interior uses of Mylonite include Decorative aggregates and Interior decoration whereas the interior uses of Granulite include Bathrooms, Countertops, Decorative aggregates, Entryways, Flooring, Homes, Hotels, Interior decoration, Kitchens and Stair treads. Due to some exceptional properties of Mylonite and Granulite, they have various applications in construction industry. The uses of Mylonite in construction industry include For road aggregate, Landscaping, Roadstone and that of Granulite include As dimension stone, Building houses or walls.
More about Mylonite and Granulite
Here you can know more about Mylonite and Granulite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mylonite and Granulite consists of mineral content and compound content. The mineral content of Mylonite includes Porphyroblasts and mineral content of Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Quartz. You can also check out the list of all . When we have to compare Mylonite vs Granulite, the texture, color and appearance plays an important role in determining the type of rock. Mylonite is available in black to grey colors whereas, Granulite is available in black, brown colors. Appearance of Mylonite is Dull, Banded and Foilated and that of Granulite is Veined or Pebbled. Properties of rock is another aspect for Mylonite vs Granulite. The hardness of Mylonite is 3-4 and that of Granulite is 6-7. The types of Mylonite are Blastomylonites, Ultramylonites and Phyllonites whereas types of Granulite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Mylonite and Granulite is white. The specific heat capacity of Mylonite is 1.50 kJ/Kg K and that of Granulite is 0.14 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 Granulite is heat resistant, wear resistant.
