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.
Diorite is a coarse-grained intrusive igneous rock which contains large interlocking and randomly oriented crystals and forms when molten lava does not reach the Earth’s surface and cools down in the Earth’s crust.

The mineral content of Aplite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz and mineral content of Diorite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, Zircon. You can also check out the list of all . When we have to compare Aplite vs Diorite, 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, Diorite is available in black, brown, light to dark grey, white colors. Appearance of Aplite is Veined or Pebbled and that of Diorite is Shiny. Properties of rock is another aspect for Aplite vs Diorite. The hardness of Aplite is 6.5 and that of Diorite is 6-7. The types of Aplite are Not Available whereas types of Diorite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Aplite is white while that of Diorite is bluish black. The specific heat capacity of Aplite is 0.79 kJ/Kg K and that of Diorite 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 Diorite is heat resistant, pressure resistant, wear resistant.
