Definition
Monzonite is a granular igneous rock with composition between syenite and diorite and containing approximately equal amounts of orthoclase and plagioclase
Mylonite is a metamorphic rock formed by ductile deformation during intense shearing encountered during folding and faulting, a process termed cataclastic or dynamic metamorphism

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

Monzonite 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. Monzonite vs Mylonite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Monzonite and Properties of Mylonite. Learn more about Monzonite vs Mylonite in the next section. The interior uses of Monzonite include Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Mylonite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Monzonite and Mylonite, they have various applications in construction industry. The uses of Monzonite in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate and that of Mylonite include For road aggregate, Landscaping, Roadstone.
More about Monzonite and Mylonite
Here you can know more about Monzonite and Mylonite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Monzonite and Mylonite consists of mineral content and compound content. The mineral content of Monzonite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, Zircon and mineral content of Mylonite includes Porphyroblasts. You can also check out the list of all Igneous Rocks. When we have to compare Monzonite vs Mylonite, the texture, color and appearance plays an important role in determining the type of rock. Monzonite is available in black, brown, light to dark grey, white colors whereas, Mylonite is available in black to grey colors. Appearance of Monzonite is Shiny and that of Mylonite is Dull, Banded and Foilated. Properties of rock is another aspect for Monzonite vs Mylonite. The hardness of Monzonite is 6-7 and that of Mylonite is 3-4. The types of Monzonite are Quartz Monzonite, Mangerite, Syenite and Diorite 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 Monzonite and Mylonite is white. The specific heat capacity of Monzonite is 0.92 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.Monzonite is heat resistant, impact resistant, pressure resistant whereas Mylonite is heat resistant, impact resistant, pressure resistant.
