Formation

Dunite is a plutonic ultramafic igneous rock consisting almost m olivine. It can be formed in two ways.

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.

More about Dunite and Turbidite

Here you can know more about Dunite and Turbidite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dunite and Turbidite consists of mineral content and compound content. The mineral content of Dunite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene and mineral content of Turbidite includes Coesite, Quartz, Sand. You can also check out the list of all Igneous Rocks. When we have to compare Dunite vs Turbidite, the texture, color and appearance plays an important role in determining the type of rock. Dunite is available in dark greenish - grey colors whereas, Turbidite is available in black, brown, green, grey, pink colors. Appearance of Dunite is Rough and Shiny and that of Turbidite is Dull and Banded. Properties of rock is another aspect for Dunite vs Turbidite. The hardness of Dunite is 3.5-4 and that of Turbidite is 3. The types of Dunite are Dunite whereas types of Turbidite are Sedimentary rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Dunite is white while that of Turbidite is white, greenish white or grey. The specific heat capacity of Dunite is 1.25 kJ/Kg K and that of Turbidite is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Dunite is heat resistant, pressure resistant, wear resistant whereas Turbidite is heat resistant.
