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.
The formation of Appinite takes place deep beneath the Earth’s surface at around 150 to 450 kms, and are erupted rapidly and violently.

Aplite vs Appinite 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 Appinite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Aplite and Properties of Appinite. Learn more about Aplite vs Appinite 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 Appinite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Aplite and Appinite, they have various applications in construction industry. The uses of Aplite in construction industry include As dimension stone and that of Appinite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Aplite and Appinite
Here you can know more about Aplite and Appinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Aplite and Appinite 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 Appinite includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Aplite vs Appinite, 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, Appinite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. Appearance of Aplite is Veined or Pebbled and that of Appinite is Dull, Banded and Foilated. Properties of rock is another aspect for Aplite vs Appinite. The hardness of Aplite is 6.5 and that of Appinite is 5-6. The types of Aplite are Not Available whereas types of Appinite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Aplite and Appinite is white. The specific heat capacity of Aplite is 0.79 kJ/Kg K and that of Appinite is Not Available. 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 Appinite is heat resistant, impact resistant.
