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

Minette 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. Minette vs Aplite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Minette and Properties of Aplite. Learn more about Minette vs Aplite in the next section. The interior uses of Minette include Countertops, 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 Minette and Aplite, they have various applications in construction industry. The uses of Minette in construction industry include As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories and that of Aplite include As dimension stone.
More about Minette and Aplite
Here you can know more about Minette and Aplite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Minette and Aplite consists of mineral content and compound content. The mineral content of Minette includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene 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 Igneous Rocks. When we have to compare Minette vs Aplite, the texture, color and appearance plays an important role in determining the type of rock. Minette is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas, Aplite is available in black, grey, orange, pink, white colors. Appearance of Minette is Dull, Banded and Foilated and that of Aplite is Veined or Pebbled. Properties of rock is another aspect for Minette vs Aplite. The hardness of Minette is 5-6 and that of Aplite is 6.5. The types of Minette are Minette, Alnoite, Camptonite, Monchiquite, Fourchite, Vogesite, Appinite and Spessartite 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 Minette and Aplite is white.
