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
Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate

Mylonite vs Limestone 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 Limestone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Mylonite and Properties of Limestone. Learn more about Mylonite vs Limestone in the next section. The interior uses of Mylonite include Decorative aggregates and Interior decoration whereas the interior uses of Limestone include Decorative aggregates and Interior decoration. Due to some exceptional properties of Mylonite and Limestone, they have various applications in construction industry. The uses of Mylonite in construction industry include For road aggregate, Landscaping, Roadstone and that of Limestone include Cement manufacture, Cobblestones, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar, Roadstone, Source of calcium.
More about Mylonite and Limestone
Here you can know more about Mylonite and Limestone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mylonite and Limestone consists of mineral content and compound content. The mineral content of Mylonite includes Porphyroblasts and mineral content of Limestone includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt. You can also check out the list of all Metamorphic Rocks. When we have to compare Mylonite vs Limestone, the texture, color and appearance plays an important role in determining the type of rock. Mylonite is available in black to grey colors whereas, Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors. Appearance of Mylonite is Dull, Banded and Foilated and that of Limestone is Rough and Banded. Properties of rock is another aspect for Mylonite vs Limestone. Hardness of Mylonite and Limestone is 3-4. The types of Mylonite are Blastomylonites, Ultramylonites and Phyllonites whereas types of Limestone are Chalk, Coquina, Fossiliferous Limestone, Lithographic Limestone, Oolitic Limestone, Travertine, Tufa. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Mylonite and Limestone is white. The specific heat capacity of Mylonite is 1.50 kJ/Kg K and that of Limestone is 0.91 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 Limestone is pressure resistant.
