Definition
Aplite is a fine-grained granite composed mainly of feldspar and quartz
Blueschist is a metamorphic rock which is generally blue in color and is formed under conditions of high pressure and low temperature

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.
Blueschist forms due to the metamorphism of basalt and other rocks with similar composition at high pressures and low temperatures and approximately corresponding to a depth of 15 to 30 kilometers and 200 to 500 °C.

Aplite vs Blueschist 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 Blueschist characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Aplite and Properties of Blueschist. Learn more about Aplite vs Blueschist 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 Blueschist include Floor tiles, Flooring, Homes, Hotels and Kitchens. Due to some exceptional properties of Aplite and Blueschist, they have various applications in construction industry. The uses of Aplite in construction industry include As dimension stone and that of Blueschist include As dimension stone, Cobblestones, Rail track ballast, Roadstone.
More about Aplite and Blueschist
Here you can know more about Aplite and Blueschist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Aplite and Blueschist 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 Blueschist includes Albite, Chlorite, Epidote, Garnet, Glaucophane, Lawsonite, Muscovite or Illite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Aplite vs Blueschist, 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, Blueschist is available in blue, bluish - grey, purple, shades of blue colors. Appearance of Aplite is Veined or Pebbled and that of Blueschist is Dull and Banded. Properties of rock is another aspect for Aplite vs Blueschist. The hardness of Aplite is 6.5 and that of Blueschist is 3.5-4. The types of Aplite are Not Available whereas types of Blueschist 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 Blueschist is white to grey. The specific heat capacity of Aplite is 0.79 kJ/Kg K and that of Blueschist 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 Blueschist is impact resistant, pressure resistant.
