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.
Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.

Aplite vs Andesite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Aplite vs Andesite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Aplite and Properties of Andesite. Learn more about Aplite vs Andesite in the next section. The interior uses of Aplite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Kitchens and Stair treads whereas the interior uses of Andesite include Decorative aggregates, Floor tiles, Homes, Interior decoration and Kitchens. Due to some exceptional properties of Aplite and Andesite, they have various applications in construction industry. The uses of Aplite in construction industry include As dimension stone and that of Andesite include Cobblestones, Construction aggregate, For road aggregate.
More about Aplite and Andesite
Here you can know more about Aplite and Andesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Aplite and Andesite 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 Andesite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite, Magnetite, Plagioclase, Pyroxene, Zircon. You can also check out the list of all Igneous Rocks. When we have to compare Aplite vs Andesite, 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, Andesite is available in bluish - grey, grey, pink, yellow colors. Appearance of Aplite is Veined or Pebbled and that of Andesite is Dull and Soft. Properties of rock is another aspect for Aplite vs Andesite. The hardness of Aplite is 6.5 and that of Andesite is 7. The types of Aplite are Not Available whereas types of Andesite are Icelandite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Aplite and Andesite is white. The specific heat capacity of Aplite is 0.79 kJ/Kg K and that of Andesite is 2.39 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 Andesite is heat resistant, pressure resistant, wear resistant.
