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
Travertine is a mineral consisting of layered calcium carbonate formed by deposition from spring waters

Formation
Mylonites are ductilely deformed rocks formed by the accumulation of large shear strain, in ductile fault zones.
Travertine is a type of sedimentary rock formed when a river carries or transports pieces of broken rock which then undergo sedimentation. They are then subjected to high temperature and pressure hence forming travertine rock.

Mylonite vs Travertine 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 Travertine characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Mylonite and Properties of Travertine. Learn more about Mylonite vs Travertine in the next section. The interior uses of Mylonite include Decorative aggregates and Interior decoration whereas the interior uses of Travertine include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Mylonite and Travertine, they have various applications in construction industry. The uses of Mylonite in construction industry include For road aggregate, Landscaping, Roadstone and that of Travertine include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate, Raw material for the manufacture of mortar.
More about Mylonite and Travertine
Here you can know more about Mylonite and Travertine. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mylonite and Travertine consists of mineral content and compound content. The mineral content of Mylonite includes Porphyroblasts and mineral content of Travertine includes Calcite, Clay, Feldspar, Micas, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Mylonite vs Travertine, the texture, color and appearance plays an important role in determining the type of rock. Mylonite is available in black to grey colors whereas, Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. Appearance of Mylonite is Dull, Banded and Foilated and that of Travertine is Fibrous. Properties of rock is another aspect for Mylonite vs Travertine. Hardness of Mylonite and Travertine is 3-4. The types of Mylonite are Blastomylonites, Ultramylonites and Phyllonites whereas types of Travertine 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 Travertine is white. The specific heat capacity of Mylonite is 1.50 kJ/Kg K and that of Travertine is 1.09 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 Travertine is impact resistant, pressure resistant, wear resistant.
