Definition
Aplite is a fine-grained granite composed mainly of feldspar and quartz
Troctolite is a mafic intrusive rock type. It consists essentially of major but variable amounts of olivine and calcic plagioclase along with minor pyroxene. It is an olivine-rich anorthosite, or a pyroxene-depleted relative of gabbro

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.
Troctolite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

More about Aplite and Troctolite
Here you can know more about Aplite and Troctolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Aplite and Troctolite 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 Troctolite includes Augite, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Aplite vs Troctolite, 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, Troctolite is available in dark grey to black colors. Appearance of Aplite is Veined or Pebbled and that of Troctolite is Veined and Shiny. Properties of rock is another aspect for Aplite vs Troctolite. The hardness of Aplite is 6.5 and that of Troctolite is 7. The types of Aplite are Not Available whereas types of Troctolite 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 Troctolite is black. The specific heat capacity of Aplite is 0.79 kJ/Kg K and that of Troctolite 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 Troctolite is impact resistant, pressure resistant, wear resistant.
