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
Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay

Formation
Mylonites are ductilely deformed rocks formed by the accumulation of large shear strain, in ductile fault zones.
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.

Mylonite vs Claystone 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 Claystone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Mylonite and Properties of Claystone. Learn more about Mylonite vs Claystone in the next section. The interior uses of Mylonite include Decorative aggregates and Interior decoration whereas the interior uses of Claystone include Decorative aggregates, Entryways, Floor tiles, Homes and Interior decoration. Due to some exceptional properties of Mylonite and Claystone, they have various applications in construction industry. The uses of Mylonite in construction industry include For road aggregate, Landscaping, Roadstone and that of Claystone include As a sintering agent in steel industry to process iron ore, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.
More about Mylonite and Claystone
Here you can know more about Mylonite and Claystone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mylonite and Claystone consists of mineral content and compound content. The mineral content of Mylonite includes Porphyroblasts and mineral content of Claystone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Mylonite vs Claystone, the texture, color and appearance plays an important role in determining the type of rock. Mylonite is available in black to grey colors whereas, Claystone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. Appearance of Mylonite is Dull, Banded and Foilated and that of Claystone is Rough and Dull. Properties of rock is another aspect for Mylonite vs Claystone. The hardness of Mylonite is 3-4 and that of Claystone is 3.5-4. The types of Mylonite are Blastomylonites, Ultramylonites and Phyllonites whereas types of Claystone 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 Claystone is white. The specific heat capacity of Mylonite is 1.50 kJ/Kg K and that of Claystone is 0.92 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 Claystone is heat resistant, impact resistant.
