Definition
Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites
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
Wehrlite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
Mylonites are ductilely deformed rocks formed by the accumulation of large shear strain, in ductile fault zones.

Wehrlite 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. Wehrlite vs Mylonite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Wehrlite and Properties of Mylonite. Learn more about Wehrlite vs Mylonite in the next section. The interior uses of Wehrlite include Decorative aggregates and Interior decoration whereas the interior uses of Mylonite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Wehrlite and Mylonite, they have various applications in construction industry. The uses of Wehrlite in construction industry include As dimension stone, Cobblestones and that of Mylonite include For road aggregate, Landscaping, Roadstone.
More about Wehrlite and Mylonite
Here you can know more about Wehrlite and Mylonite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Wehrlite and Mylonite consists of mineral content and compound content. The mineral content of Wehrlite includes Pyroxene and mineral content of Mylonite includes Porphyroblasts. You can also check out the list of all Igneous Rocks. When we have to compare Wehrlite vs Mylonite, the texture, color and appearance plays an important role in determining the type of rock. Wehrlite is available in dark greenish - grey, green colors whereas, Mylonite is available in black to grey colors. Appearance of Wehrlite is Rough and Banded and that of Mylonite is Dull, Banded and Foilated. Properties of rock is another aspect for Wehrlite vs Mylonite. The hardness of Wehrlite is 5.5-6 and that of Mylonite is 3-4. The types of Wehrlite are Not Available 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 Wehrlite and Mylonite is white. The specific heat capacity of Wehrlite is 0.63 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.Wehrlite is heat resistant, impact resistant, pressure resistant whereas Mylonite is heat resistant, impact resistant, pressure resistant.
