Dunite vs Pyroxenite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Dunite and Pyroxenite Reserves. Dunite is a green to brownish coarse-grained igneous rock mainly consisting of olivine. Pyroxenite is a dark, greenish, granular intrusive igneous rock consisting mainly of pyroxenes and olivine. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Dunite vs Pyroxenite information and Dunite vs Pyroxenite characteristics in the upcoming sections.

Dunite vs Pyroxenite 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. Dunite vs Pyroxenite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Dunite and Properties of Pyroxenite. Learn more about Dunite vs Pyroxenite in the next section. The interior uses of Dunite include Decorative aggregates and Interior decoration whereas the interior uses of Pyroxenite include Countertops, Decorative aggregates, Interior decoration and Kitchens. Due to some exceptional properties of Dunite and Pyroxenite, they have various applications in construction industry. The uses of Dunite in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar and that of Pyroxenite include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.

More about Dunite and Pyroxenite

Here you can know more about Dunite and Pyroxenite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dunite and Pyroxenite 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 Pyroxenite includes Amphibole, Augite, Bronzite, Chromite, Diopside, Enstatite, Garnet, Hornblende, Hypersthene, Magnetite, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Dunite vs Pyroxenite, the texture, color and appearance plays an important role in determining the type of rock. Dunite is available in dark greenish - grey colors whereas, Pyroxenite is available in black to grey, bluish - grey, dark greenish - grey, green, light greenish grey colors. Appearance of Dunite is Rough and Shiny and that of Pyroxenite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Dunite vs Pyroxenite. The hardness of Dunite is 3.5-4 and that of Pyroxenite is 7. The types of Dunite are Not Available whereas types of Pyroxenite are Clinopyroxenites, Orthopyroxenites and Websterites. 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 Pyroxenite is white, greenish white or grey. The specific heat capacity of Dunite is 1.25 kJ/Kg K and that of Pyroxenite is Not Available. 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 Pyroxenite is impact resistant, pressure resistant, wear resistant.
