Conglomerate 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. Conglomerate vs Dunite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Conglomerate and Properties of Dunite. Learn more about Conglomerate vs Dunite in the next section. The interior uses of Conglomerate include Decorative aggregates, Floor tiles and Homes whereas the interior uses of Dunite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Conglomerate and Dunite, they have various applications in construction industry. The uses of Conglomerate in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Roadstone 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 Conglomerate and Dunite
Here you can know more about Conglomerate and Dunite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Conglomerate and Dunite consists of mineral content and compound content. The mineral content of Conglomerate includes Clay, Sand, Silica, Silt 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 Conglomerate vs Dunite, the texture, color and appearance plays an important role in determining the type of rock. Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors whereas, Dunite is available in dark greenish - grey colors. Appearance of Conglomerate is Shiny and Rounded and that of Dunite is Rough and Shiny. Properties of rock is another aspect for Conglomerate vs Dunite. The hardness of Conglomerate is 2-3 and that of Dunite is 3.5-4. The types of Conglomerate 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 Conglomerate and Dunite is white. The specific heat capacity of Conglomerate 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.Conglomerate is heat resistant whereas Dunite is heat resistant, pressure resistant, wear resistant.
