Formation

Turbidite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles then settle down and are subjected to high temperature and pressures hence forming Turbidite.

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 Turbidite and Blueschist

Here you can know more about Turbidite and Blueschist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Turbidite and Blueschist consists of mineral content and compound content. The mineral content of Turbidite includes Coesite, Quartz, Sand 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 Sedimentary Rocks. When we have to compare Turbidite vs Blueschist, the texture, color and appearance plays an important role in determining the type of rock. Turbidite is available in black, brown, green, grey, pink colors whereas, Blueschist is available in blue, bluish - grey, purple, shades of blue colors. Appearance of Turbidite is Dull and Banded and that of Blueschist is Dull and Banded. Properties of rock is another aspect for Turbidite vs Blueschist. The hardness of Turbidite is 3 and that of Blueschist is 3.5-4. The types of Turbidite are Sedimentary 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 Turbidite is white, greenish white or grey while that of Blueschist is white to grey. The specific heat capacity of Turbidite is 0.92 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.Turbidite is heat resistant whereas Blueschist is impact resistant, pressure resistant.
