Dunite vs Amphibolite

Dunite vs Amphibolite 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 Amphibolite Reserves. Dunite is a green to brownish coarse-grained igneous rock mainly consisting of olivine. Amphibolite can be defined as a granular metamorphic rock which mainly consist of hornblende and plagioclase. 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 Amphibolite information and Dunite vs Amphibolite characteristics in the upcoming sections.

Dunite vs Amphibolite 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 Amphibolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Dunite and Properties of Amphibolite. Learn more about Dunite vs Amphibolite in the next section. The interior uses of Dunite include Decorative aggregates and Interior decoration whereas the interior uses of Amphibolite include Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels and Kitchens. Due to some exceptional properties of Dunite and Amphibolite, 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 Amphibolite include As dimension stone, Building houses or walls, Cobblestones, Construction aggregate, For road aggregate, Landscaping, Production of glass and ceramics, Roadstone.

More about Dunite and Amphibolite

Here you can know more about Dunite and Amphibolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dunite and Amphibolite 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 Amphibolite includes Amphibole, Andalusite, Biotite, Calcite, Epidote, Garnet, Hornblade, Kyanite, Magnetite, Olivine, Plagioclase, Pyroxene, Staurolite, Wollastonite. You can also check out the list of all Igneous Rocks. When we have to compare Dunite vs Amphibolite, the texture, color and appearance plays an important role in determining the type of rock. Dunite is available in dark greenish - grey colors whereas, Amphibolite is available in black, brown, green, grey colors. Appearance of Dunite is Rough and Shiny and that of Amphibolite is Foliated. Properties of rock is another aspect for Dunite vs Amphibolite. The hardness of Dunite is 3.5-4 and that of Amphibolite is 6-7. The types of Dunite are Dunite whereas types of Amphibolite are Hornblendite. 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 Amphibolite is white to grey. The specific heat capacity of Dunite is 1.25 kJ/Kg K and that of Amphibolite is 0.84 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 Amphibolite is heat resistant, pressure resistant, wear resistant.
