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

Turbidite vs Dunite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Turbidite vs Dunite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Turbidite and Properties of Dunite. Learn more about Turbidite vs Dunite in the next section. The interior uses of Turbidite include Bathrooms, Countertops, Decorative aggregates, Flooring, Homes and Interior decoration whereas the interior uses of Dunite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Turbidite and Dunite, they have various applications in construction industry. The uses of Turbidite in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement and that of Dunite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.
More about Turbidite and Dunite
Here you can know more about Turbidite and Dunite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Turbidite and Dunite consists of mineral content and compound content. The mineral content of Turbidite includes Coesite, Quartz, Sand and mineral content of Dunite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Turbidite vs Dunite, the texture, color and appearance plays an important role in determining the type of rock. Turbidite is available in black, brown, colourless, green, grey, pink colors whereas, Dunite is available in dark greenish - grey colors. Appearance of Turbidite is Dull and Banded and that of Dunite is Rough and Shiny. Properties of rock is another aspect for Turbidite vs Dunite. The hardness of Turbidite is 3 and that of Dunite is 3.5-4. The types of Turbidite are Not Available whereas types of Dunite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Turbidite and Dunite is white, greenish white or grey. The specific heat capacity of Turbidite is 0.92 kJ/Kg K and that of Dunite is 1.25 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 Dunite is heat resistant, pressure resistant, wear resistant.
