Formation
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Metapelite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
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.

Metapelite 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. Metapelite vs Aplite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Metapelite and Properties of Aplite. Learn more about Metapelite vs Aplite in the next section. The interior uses of Metapelite include Decorative aggregates and Interior decoration 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 Metapelite and Aplite, they have various applications in construction industry. The uses of Metapelite in construction industry include Cement manufacture, Construction aggregate, For road aggregate and that of Aplite include As dimension stone.
More about Metapelite and Aplite
Here you can know more about Metapelite and Aplite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Metapelite and Aplite consists of mineral content and compound content. The mineral content of Metapelite includes Albite, Chlorite, Quartz 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 Metapelite vs Aplite, the texture, color and appearance plays an important role in determining the type of rock. Metapelite is available in dark greenish - grey, green, light green, light greenish grey colors whereas, Aplite is available in black, grey, orange, pink, white colors. Appearance of Metapelite is Banded and that of Aplite is Veined or Pebbled. Properties of rock is another aspect for Metapelite vs Aplite. The hardness of Metapelite is 5-6 and that of Aplite is 6.5. The types of Metapelite are Not Available whereas types of Aplite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Metapelite is unknown while that of Aplite is white. The specific heat capacity of Metapelite is 0.72 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.Metapelite is heat resistant, impact resistant, pressure resistant whereas Aplite is heat resistant, wear resistant.
