Formation

Granodiorite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental 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 Granodiorite and Blueschist

Here you can know more about Granodiorite and Blueschist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granodiorite and Blueschist consists of mineral content and compound content. The mineral content of Granodiorite 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 Granodiorite vs Blueschist, the texture, color and appearance plays an important role in determining the type of rock. Granodiorite is available in black, grey, orange, pink, white colors whereas, Blueschist is available in blue, bluish - grey, purple, shades of blue colors. Appearance of Granodiorite is Veined or Pebbled and that of Blueschist is Dull and Banded. Properties of rock is another aspect for Granodiorite vs Blueschist. The hardness of Granodiorite is 6 and that of Blueschist is 3.5-4. The types of Granodiorite are Granodiorite 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 Granodiorite is white while that of Blueschist is white to grey. The specific heat capacity of Granodiorite is 0.79 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.Granodiorite is heat resistant, wear resistant whereas Blueschist is impact resistant, pressure resistant.
