Definition
Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate
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
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.
Mylonites are ductilely deformed rocks formed by the accumulation of large shear strain, in ductile fault zones.

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