Formation
Kimberlite is an igneous rock and is the main source of diamonds. Its formation takes place deep beneath the Earth’s surface between 150 to 450 kilometres, 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.

More about Kimberlite and Aplite
Here you can know more about Kimberlite and Aplite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Kimberlite and Aplite consists of mineral content and compound content. The mineral content of Kimberlite includes Garnet, 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 Kimberlite vs Aplite, the texture, color and appearance plays an important role in determining the type of rock. Kimberlite 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 Kimberlite is Dull and Banded and that of Aplite is Veined or Pebbled. Properties of rock is another aspect for Kimberlite vs Aplite. The hardness of Kimberlite is 6-7 and that of Aplite is 6.5. The types of Kimberlite are Basaltic Kimberlites and Micaceous Kimberlites 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 Kimberlite and Aplite is white. The specific heat capacity of Kimberlite is 0.92 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.Kimberlite is heat resistant, impact resistant whereas Aplite is heat resistant, wear resistant.
