Formation

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.

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.

More about Blueschist and Aplite

Here you can know more about Blueschist and Aplite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Blueschist and Aplite consists of mineral content and compound content. The mineral content of Blueschist includes Albite, Chlorite, Epidote, Garnet, Glaucophane, Lawsonite, Muscovite or Illite, Quartz and mineral content of Aplite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Blueschist vs Aplite, the texture, color and appearance plays an important role in determining the type of rock. Blueschist is available in blue, bluish - grey, purple, shades of blue colors whereas, Aplite is available in black, grey, orange, pink, white colors. Appearance of Blueschist is Dull and Banded and that of Aplite is Veined or Pebbled. Properties of rock is another aspect for Blueschist vs Aplite. The hardness of Blueschist is 3.5-4 and that of Aplite is 6.5. The types of Blueschist are Metamorphic rock whereas types of Aplite are Igneous rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Blueschist is white to grey while that of Aplite is white. The specific heat capacity of Blueschist is 0.84 kJ/Kg K and that of Aplite is 0.79 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Blueschist is impact resistant, pressure resistant whereas Aplite is heat resistant, wear resistant.
