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.

Dunite is a plutonic ultramafic igneous rock consisting almost m olivine. It can be formed in two ways.

More about Aplite and Dunite

Here you can know more about Aplite and Dunite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Aplite and Dunite 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 Dunite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Aplite vs Dunite, 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, Dunite is available in dark greenish - grey colors. Appearance of Aplite is Veined or Pebbled and that of Dunite is Rough and Shiny. Properties of rock is another aspect for Aplite vs Dunite. The hardness of Aplite is 6.5 and that of Dunite is 3.5-4. The types of Aplite are Igneous rock whereas types of Dunite are Dunite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Aplite and Dunite is white. The specific heat capacity of Aplite is 0.79 kJ/Kg K and that of Dunite is 1.25 kJ/Kg K. 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 Dunite is heat resistant, pressure resistant, wear resistant.
