Archaeological Significance
Formation
Migmatites form by high temperature regional and thermal metamorphism of protolith rocks where rocks melt partially due to high temperature.
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.

Migmatite vs Aplite 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. Migmatite vs Aplite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Migmatite and Properties of Aplite. Learn more about Migmatite vs Aplite in the next section. The interior uses of Migmatite include Countertops, Flooring and Kitchens whereas the interior uses of Aplite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Kitchens and Stair treads. Due to some exceptional properties of Migmatite and Aplite, they have various applications in construction industry. The uses of Migmatite in construction industry include As dimension stone, Cement manufacture, For road aggregate, Making natural cement and that of Aplite include As dimension stone.
More about Migmatite and Aplite
Here you can know more about Migmatite and Aplite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Migmatite and Aplite consists of mineral content and compound content. The mineral content of Migmatite includes Biotite, Chlorite, Feldspar, Garnet, Graphite, Hornblade, Micas, Muscovite or Illite, Quartz, Quartzite, Silica, Zircon and mineral content of Aplite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Migmatite vs Aplite, the texture, color and appearance plays an important role in determining the type of rock. Migmatite is available in black, bluish - grey, brown, brown- black, dark greenish - grey, dark grey to black colors whereas, Aplite is available in black, grey, orange, pink, white colors. Appearance of Migmatite is Dull, Banded and Foilated and that of Aplite is Veined or Pebbled. Properties of rock is another aspect for Migmatite vs Aplite. The hardness of Migmatite is 5.5-6.5 and that of Aplite is 6.5. The types of Migmatite are Diatexites and Metatexites whereas types of Aplite are Igneous rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Migmatite and Aplite is white. The specific heat capacity of Migmatite is 0.79 kJ/Kg K and that of Aplite is 0.79 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Migmatite is heat resistant, pressure resistant whereas Aplite is heat resistant, wear resistant.
