Definition
Aplite is a fine-grained granite composed mainly of feldspar and quartz
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
Aplites belong to intrusive igneous rocks which are mostly quart and alkali feldspar and are formed from residual eutectic granitic liquids and represent the final crystallization products of magma.
Mylonites are ductilely deformed rocks formed by the accumulation of large shear strain, in ductile fault zones.

Aplite 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. Aplite vs Mylonite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Aplite and Properties of Mylonite. Learn more about Aplite vs Mylonite in the next section. The interior uses of Aplite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Kitchens and Stair treads whereas the interior uses of Mylonite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Aplite and Mylonite, they have various applications in construction industry. The uses of Aplite in construction industry include As dimension stone and that of Mylonite include For road aggregate, Landscaping, Roadstone.
More about Aplite and Mylonite
Here you can know more about Aplite and Mylonite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Aplite and Mylonite consists of mineral content and compound content. The mineral content of Aplite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz and mineral content of Mylonite includes Porphyroblasts. You can also check out the list of all Igneous Rocks. When we have to compare Aplite vs Mylonite, the texture, color and appearance plays an important role in determining the type of rock. Aplite is available in black, grey, orange, pink, white colors whereas, Mylonite is available in black to grey colors. Appearance of Aplite is Veined or Pebbled and that of Mylonite is Dull, Banded and Foilated. Properties of rock is another aspect for Aplite vs Mylonite. The hardness of Aplite is 6.5 and that of Mylonite is 3-4. The types of Aplite are Igneous rock 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 Aplite and Mylonite is white. The specific heat capacity of Aplite is 0.79 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.Aplite is heat resistant, wear resistant whereas Mylonite is heat resistant, impact resistant, pressure resistant.
