Formation
Peridotites can be formed in two ways: as mantle rocks formed during the accretion and differentiation of the Earth or as cumulate rocks formed by precipitation of olivine and pyroxenes from basaltic magmas.
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.

Peridotite vs Turbidite 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. Peridotite vs Turbidite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Peridotite and Properties of Turbidite. Learn more about Peridotite vs Turbidite in the next section. The interior uses of Peridotite include Decorative aggregates and Interior decoration whereas the interior uses of Turbidite include Bathrooms, Countertops, Decorative aggregates, Flooring, Homes and Interior decoration. Due to some exceptional properties of Peridotite and Turbidite, they have various applications in construction industry. The uses of Peridotite in construction industry include As dimension stone, Cobblestones and that of Turbidite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement.
More about Peridotite and Turbidite
Here you can know more about Peridotite and Turbidite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Peridotite and Turbidite consists of mineral content and compound content. The mineral content of Peridotite 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 Peridotite vs Turbidite, the texture, color and appearance plays an important role in determining the type of rock. Peridotite is available in dark greenish - grey colors whereas, Turbidite is available in black, brown, colourless, green, grey, pink colors. Appearance of Peridotite is Rough and Shiny and that of Turbidite is Dull and Banded. Properties of rock is another aspect for Peridotite vs Turbidite. The hardness of Peridotite is 5.5-6 and that of Turbidite is 3. The types of Peridotite are Dunite, Wehrlite, Harzburgite, Lherzolite and Pyrolite whereas types of Turbidite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Peridotite is white while that of Turbidite is white, greenish white or grey. The specific heat capacity of Peridotite is 1.26 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.Peridotite is heat resistant, pressure resistant, wear resistant whereas Turbidite is heat resistant.
