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
Monzonite is a granular igneous rock with composition between syenite and diorite and containing approximately equal amounts of orthoclase and plagioclase

Formation
Mylonites are ductilely deformed rocks formed by the accumulation of large shear strain, in ductile fault zones.
Monzonite 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.

The uses of Mylonite in construction industry include For road aggregate, Landscaping, Roadstone and that of Monzonite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate.
More about Mylonite and Monzonite
Here you can know more about Mylonite and Monzonite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mylonite and Monzonite consists of mineral content and compound content. The mineral content of Mylonite includes Porphyroblasts and mineral content of Monzonite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, Zircon. You can also check out the list of all Metamorphic Rocks. When we have to compare Mylonite vs Monzonite, the texture, color and appearance plays an important role in determining the type of rock. Mylonite is available in black to grey colors whereas, Monzonite is available in black, brown, light to dark grey, white colors. Appearance of Mylonite is Dull, Banded and Foilated and that of Monzonite is Shiny. Properties of rock is another aspect for Mylonite vs Monzonite. The hardness of Mylonite is 3-4 and that of Monzonite is 6-7. The types of Mylonite are Blastomylonites, Ultramylonites and Phyllonites whereas types of Monzonite are Quartz Monzonite, Mangerite, Syenite and Diorite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Mylonite and Monzonite is white. The specific heat capacity of Mylonite is 1.50 kJ/Kg K and that of Monzonite 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 Monzonite is heat resistant, impact resistant, pressure resistant.
