Formation
Pyroxenites are ultramafic igneous rocks which are made up of minerals of the pyroxene group, such as augite and diopside, hypersthene, bronzite or enstatite.
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.

Pyroxenite 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. Pyroxenite vs Turbidite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Pyroxenite and Properties of Turbidite. Learn more about Pyroxenite vs Turbidite in the next section. The interior uses of Pyroxenite include Countertops, Decorative aggregates, Interior decoration and Kitchens whereas the interior uses of Turbidite include Bathrooms, Countertops, Decorative aggregates, Flooring, Homes and Interior decoration. Due to some exceptional properties of Pyroxenite and Turbidite, they have various applications in construction industry. The uses of Pyroxenite in construction industry include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate and that of Turbidite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement.
More about Pyroxenite and Turbidite
Here you can know more about Pyroxenite and Turbidite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pyroxenite and Turbidite consists of mineral content and compound content. The mineral content of Pyroxenite includes Amphibole, Augite, Bronzite, Chromite, Diopside, Enstatite, Garnet, Hornblende, Hypersthene, Magnetite, 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 Pyroxenite vs Turbidite, the texture, color and appearance plays an important role in determining the type of rock. Pyroxenite is available in black to grey, bluish - grey, dark greenish - grey, green, light greenish grey colors whereas, Turbidite is available in black, brown, colourless, green, grey, pink colors. Appearance of Pyroxenite is Layered, Banded, Veined and Shiny and that of Turbidite is Dull and Banded. Properties of rock is another aspect for Pyroxenite vs Turbidite. The hardness of Pyroxenite is 7 and that of Turbidite is 3. The types of Pyroxenite are Clinopyroxenites, Orthopyroxenites and Websterites 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 Pyroxenite and Turbidite is white, greenish white or grey. The specific heat capacity of Pyroxenite is Not Available 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.Pyroxenite is impact resistant, pressure resistant, wear resistant whereas Turbidite is heat resistant.
