Formation
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
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 Charnockite and Blueschist
Here you can know more about Charnockite and Blueschist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Charnockite and Blueschist consists of mineral content and compound content. The mineral content of Charnockite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Olivine, 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 Charnockite vs Blueschist, the texture, color and appearance plays an important role in determining the type of rock. Charnockite is available in black, grey, orange, pink, white colors whereas, Blueschist is available in blue, bluish - grey, purple, shades of blue colors. Appearance of Charnockite is Veined or Pebbled and that of Blueschist is Dull and Banded. Properties of rock is another aspect for Charnockite vs Blueschist. The hardness of Charnockite is 6-7 and that of Blueschist is 3.5-4. The types of Charnockite are Enderbite 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 Charnockite is white while that of Blueschist is white to grey.
