Formation

Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.

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.

More about Granulite and Blueschist

Here you can know more about Granulite and Blueschist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granulite and Blueschist consists of mineral content and compound content. The mineral content of Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, 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 Metamorphic Rocks. When we have to compare Granulite vs Blueschist, the texture, color and appearance plays an important role in determining the type of rock. Granulite is available in black, brown colors whereas, Blueschist is available in blue, bluish - grey, purple, shades of blue colors. Appearance of Granulite is Veined or Pebbled and that of Blueschist is Dull and Banded. Properties of rock is another aspect for Granulite vs Blueschist. The hardness of Granulite is 6-7 and that of Blueschist is 3.5-4. The types of Granulite are Metamorphic rock whereas types of Blueschist are Metamorphic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granulite is white while that of Blueschist is white to grey. The specific heat capacity of Granulite is 0.14 kJ/Kg K and that of Blueschist is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Granulite is heat resistant, wear resistant whereas Blueschist is impact resistant, pressure resistant.
