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.
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.

More about Aplite and Scoria
Here you can know more about Aplite and Scoria. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Aplite and Scoria 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 Scoria includes Apatite, Biotite, Calcite, Feldspar, Hematite, Hornblade, Ilmenite, Magnetite, Olivine, Pyroxene, Quartz, Silica. You can also check out the list of all Igneous Rocks. When we have to compare Aplite vs Scoria, 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, Scoria is available in black, brown, dark grey to black, red colors. Appearance of Aplite is Veined or Pebbled and that of Scoria is Glassy and Vesicular. Properties of rock is another aspect for Aplite vs Scoria. The hardness of Aplite is 6.5 and that of Scoria is 5-6. The types of Aplite are Not Available whereas types of Scoria are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Aplite and Scoria is white.
